Description

It would be nice if the folding indicators would signify the presence of errors in their elided range, currently I can see in the gutter that some errors are somewhere in my viewport, but no clue where. (Yes F8 or consulting the problems pane would help here, but that's not always what I want)

Research direction
Look into the VS Code folding provider implementation (likely in src/vs/workbench/contrib/folding) and how error diagnostics are decorated in the gutter. The issue suggests adding error indicators to folding controls. Review existing decoration handling for errors and extend it to folding glyphs. There are two comments in the issue that may provide additional context.
