ToggleCalloutdoes not handleJSDisconnectedException.Every other interop call in this file wraps the call and ignores
JSDisconnectedException: Line 407, Line 577, Line 588, Line 621, Line 632, and Line 744.ToggleCalloutcallsBitCalloutToggleCalloutwithout that guard.Two paths make this reachable.
OpenCalloutandCloseCalloutawaitToggleCallout, so on a Blazor Server circuit that is tearing down, the exception propagates out of the event handler.OnSetIsOpenat Line 557 starts it with_ = ToggleCallout();, so the exception lands on an unobserved task instead of any handler.Apply the same guard used elsewhere in the file.

455-461: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winArrow-key opening leaves the focus on the button.
HandleOnButtonKeyDownopens the callout forArrowDownandArrowUp.OpenCalloutthen callsFocusCalloutIfNeeded, which returns immediately whenAutoFocusis false. A keyboard user who opens the menu with an arrow key therefore keeps the focus on the trigger. The established pattern for a trigger witharia-haspopupis that an arrow key opens the popup and moves the focus into it.The content stays reachable with Tab, so this degrades the experience rather than blocking it. Consider moving the focus into the callout for the arrow-key path regardless of
AutoFocus.♿ Proposed change

decision treat absent identifiers identically.
In `@src/BlazorUI/Bit.BlazorUI/Components/Navs/DropMenu/BitDropMenu.scss`:
- Line 176: Insert an empty line immediately before the double-slash comment in
the DropMenu SCSS so it satisfies the
scss/double-slash-comment-empty-line-before stylelint rule.
In
`@src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Navs/DropMenu/BitDropMenuTests.cs`:
- Around line 1303-1310: Update the hover-close assertion in the relevant
BitDropMenu test to use the file’s existing WaitForAssertion pattern after
MouseLeave, waiting until aria-expanded on .bit-drm-btn becomes "false" instead
of asserting synchronously.
- Around line 1438-1456: Update BitDropMenuShouldWaitOutTheHoverOpenDelay to
remove the immediate closed-state assertion and the Task.Delay wall-clock sleep,
then change the test signature from async Task to void and retain
WaitForAssertion to verify the menu eventually opens.

Nitpick comments:
In `@src/BlazorUI/Bit.BlazorUI/Scripts/Utils.ts`:
- Around line 154-183: Refactor preventDefaultKeys and disposePreventDefaultKeys
to use an AbortController, following the existing setupFocusTrap pattern. Store
only the controller in _preventedKeys, register the keydown listener with its
signal, and abort/delete the prior controller when replacing or disposing the
registration so no HTMLElement reference is retained.
In
`@src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Navs/DropMenu/BitDropMenuTests.cs`:
- Around line 998-1001: Move the private helper methods CountCalloutToggles and
CountInvocations to the end of the test class, after the final test method,
without changing their implementations or the existing test order.
- Around line 563-590: Rename
BitDropMenuShouldNotRegisterTheSwipesWithoutTheResponsiveMode to reflect that it
verifies swipe registration with responsive mode enabled and disposal when it is
disabled, such as
BitDropMenuShouldRegisterAndDisposeTheSwipesWithTheResponsiveMode; preserve all
existing assertions.
- Around line 1459-1477: Update BitDropMenuShouldDropAHoverThePointerTookBack to
store the configured HoverOpenDelay value and derive the awaited delay from it
with sufficient margin, rather than using a hard-coded 200 ms sleep. Add a brief
comment documenting that the wait must exceed HoverOpenDelay before asserting
aria-expanded remains false.
- Around line 556-561: Document the JavaScript interop argument mappings in the
assertions for BitBlazorUI.Swipes.setup, including that index 2 is position and
index 4 is orientationLock; also document the BitBlazorUI.Callouts.toggle
mapping where index 10 represents scrollContainerId and receives the callout ID,
using concise comments or named assertion helpers without changing the existing
indexes or behavior.
