Spell Checking Not Working With Chrome Bootstrap

[dbuechel]

A user of our product has reported that spell checking is not working anymore in our latest release version (which includes the switch from Alloy to Chrome bootstrap): SafeExamBrowser/seb-win-refactoring#1205. I have updated CefSharp to the latest version 138 and can still reproduce the issue (using e.g. https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Global_attributes/spellcheck); furthermore spell checking appears to work perfectly fine both in the CEF Sample Application and the CefSharp Minimal Example for version 138.

We do not have any custom code related to spell checking (apart from a simple switch to disable it completely using the "disable-spell-checking" command-line argument). Trying to enable the spell checking via the preferences of the global request context has unfortunately not worked:

requestContext.SetPreference("browser.enable_spellchecking", true, out var message);

Is there anything new that we need to enable resp. implement to make the spell checking work again as it did previously with the Alloy runtime?

requestContext.SetPreference("browser.enable_spellchecking", true, out var message);

That shouldn't be nessicary, Chrome style should have it enabled by default.

Is there anything new that we need to enable resp. implement to make the spell checking work again as it did previously with the Alloy runtime?

Not that I'm aware of. The MinimalExample doesn't do anything special.

Are there any errors in the log file?

You might need to ask on ceforum.

Thanks for the reply. Unfortunately not, there are no errors nor anything immediately resp. obviously related to spell checking. Could it have something to do with the wrapping we need to do for the popup handling (see https://github.com/SafeExamBrowser/seb-win-refactoring/tree/master/SafeExamBrowser.Browser/Wrapper)?

I'm not familiar with your code base so it's impossible for me to say. Removing all your custom handlers is probably worth a go to start wiht.
