Windows: Expose caret position for accessibility with OSR

[magreenblatt]

Original report by Andrew Smith (Bitbucket: Andrew Smith).

• Run the CefClient app using OSR.

e.g. cefclient.exe --multi-threaded-message-loop --no-sandbox --off-screen-rendering-enabled --enable-gpu

• Run the Windows magnifier app

• Ensure that the magnifier settings are such that it will follow the text cursor

  

• Click in the search box within the google webpage in the running cefclient app
• Start typing

RESULTS:

The portion of the screen where the caret is within the input of the webpage is not rendered in the magnifier. If you click in the address bar in that app and type it will. Similarly if you run the cefclient without osr enabled it will work. Presumably something needs to be calling SetCaretPos based on the caret position.

This was tested using the 100.0.22 version of the cef client binary.

Indeed, this is something that would need to be exposed by the CEF API and implemented by the client application (same with any other accessibility feature + OSR).

I use CEF API to get access to it which means CEF API is exactly needed for this to work fine by gba
