CKEditor 5 Fullscreen is not getting full height with Source

I have updated CSS file in ckeditor5_fullscreen_full_height_source_d10_4.patch because selector :is() seems to not work.

I have updated again code because .CodeMirror class in some pages have style height: auto and other min-height: 300px . I don't understand why the same module in different pages has different styles and also, where are they comming from. So I have updated the patch fixing it.

@sararellano, can you try the latest dev → version to see if this remedies your issues?

I've tested this patch- ckeditor5_fullscreen_full_height_source_d10_5.patch on Drupal version- 10.0.12-dev, I was able to reproduce this issue (added before result) but while applying the patch, the patch wasn't applied successfully. Sharing the error here I am getting while applying the patch.

Can you try the latest dev version → and see if this is resolved? I've tested with the source plugin and also the Codemirror plugin, both in Gin and Claro. Hopefully this will take care of it.

This is what seems to be currently working for me.

Not sure the last patch was the correct solution, at least for the problem I'm seeing. Seems to me this isn't a CSS issue but a problem with codemirror not updating what's displayed when we transition to fullscreen.

What I observe:
1.) I click source button to view codemirror display.
2.) I then click the fullscreen button, page is maximized but the codemirror output is the same as it was before I hit fullscreen, not displaying all of the code.
3.) If I click on the editing area codemirror will do its update and the full source will be displayed.

If I look at the HTML source in the inspector at the div with the class CodeMirror-code before #3 the re will just be divs for the lines displayed, after the missing lines will be added to that div.
