Gmail's new email dialog

Starting with Safari 18.3 (and STP 210), Gmail's new email compose field is inaccessible via VoiceOver. 

The entire new email dialog (see attached screenshot) is not part of the accessibility tree. 

I am not able to navigate to that dialog with VoiceOver. If I place the cursor in the email compose field using my mouse pointer, VoiceOver is able to announce the text around my cursor. However, if I navigate to any other element on the page, I am not able to navigate back to the email compose field.

This issue only reproduces when the new email dialog is not full-screen/maximized. I am able to consistently reproduce this issue across multiple machines, running either Safari 18.3 or STP 210 (or newer). This issue is not reproducible on Safari 18.2 and STP 209.
