Issue Resolved / Feature Added

Fixes an issue where WizardPanels' panel-level aria-label (title + subtitle) interrupts child item TTS during rapid navigation on webOS devices with Audio Guidance enabled.

Resolution

When noSubtitle prop is set to true, the subtitle is now excluded from the computed aria-label in addition to hiding it from the UI.

Problem Detail:
When navigating quickly through items in a WizardPanels (e.g., Wi-Fi network list), the webOS Audio Guidance system prepends the panel's aria-label to every focused child element's TTS text. With {clear: true} on each focus event, the long panel subtitle is spoken repeatedly, cutting off the actual item content (e.g., SSID names) before it can be heard.

TTS Log Example:

tts speak {clear:true, text:"Wi-Fi Connection Connect to the internet... iptime5G_Official not connected"}
tts speak {clear:true, text:"Wi-Fi Connection Connect to the internet... NETGEAR45 not connected"}
(23 calls, each interrupted before SSID is spoken)

Code Change:

• Modified computed['aria-label'] in WizardPanels.js to check noSubtitle prop
• When noSubtitle is true, subtitle is excluded from aria-label
• Added .trim() to handle empty subtitle case
