Folding/Unfolding Glitch as well as CSS color palettes not showing all of a sudden

[DYT5131]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version:
• OS Version:

Steps to Reproduce:

Hi, all of a sudden, I am unable to collapse (fold or unfold) functions in html files and in css files, the small color boxes that show the pallettes are not showing. They show for some rules but do not for others which is weird. I do not see anything wrong with my code. This has happened to me before but got resolved on its own. Not sure if you fixed it.

What is the editor language mode shown in the status bar? Maybe some extension added a new language for the given file extension.
Also run with extensions disabled to make sure it is not an extension that causes that.

Hi, The language is HTML on the bottom status bar. I have tried disabling the extensions but the issue persists. Whenever I add more code to the file, it stops folding functions properly and the folding arrows are missing. No matter what code I add, it does this. It is as if there is some sort of a limit to how much code you can have in one file. I have around 30,000 lines of code in the file. I like to keep all my code in one file. Please let me know what you think. Thank you. Kind regards, Don

We have a maximum number of folding regions per file (for performance reasons). You see a warning icon on the language selector when that is reached.
There is a setting you can change: editor.foldingMaximumRegions

The same for the color decorators: editor.colorDecoratorsLimit

Please let me know if that explains what you see.
