Attachment: Bug 2017159 - Include subtitle in alertdialog aria-labelledby for onboarding screens r=pdahiya

The onboarding model picker dialog's subtitle ("Pick a model to power Smart Window") was not announced by screen readers. The <main role="alertdialog"> only referenced the title <h1> via aria-labelledby, while the subtitle <h2 id="mainContentSubheader"> was only reachable through aria-describedby="mainContentInner", which points to the entire inner content container. Screen readers don't reliably announce description text from large containers with interactive children.

Adding mainContentSubheader to aria-labelledby ensures the subtitle is announced as part of the dialog's accessible name. When no subtitle exists, the missing ID reference is safely ignored.

Verified as fixed in our latest Nightly 151.0a1 (2026-03-30), however I did notice that the entire text from the Onboarding model is read twice, not sure if its an issue or not.
