We have discovered an accessibility issue while testing our software, Tinymce's Preview Plugin, which interacts with various browsers that utilise the WebKit and Chromium engine

The issue arises when navigating the Preview plugin's web area using screen readers, such as VoiceOver on Mac. The reader needs to indicate that the user is in the web area. This results in users needing help understanding their current position within the webpage.

This problem was replicated on multiple platforms and browsers, including Safari, Chrome, and Firefox on both MacOS and Windows. A stripped-down version of the iframe replicating the issue can be found at: https://fiddle.tiny.cloud/GAiaab.

After thorough testing, the issue resides in the interaction between screen readers and the browsers rather than being specific to our software.

Steps to Reproduce:

Create content in Tinymce
Open File -> Preview
Activate Voiceover on Mac (Cmd+F5)
Navigate to the frame of the Preview screen (Tab key)
Enter the web area of Preview (Ctrl+Option+Shift+Down Arrow)

Expected Results:
Upon entering the web area, the screen reader should announce: "You are currently in a web area on a Text Element" or anything that mentions the inner content.

Actual Results:
The screen reader does not read anything when initially entering the web area.
