Description felipelorenzzon 2022-06-01 20:30:08 UTC

STEPS TO REPRODUCE
1. Open a code file (I mainly edit React .js files, but this seems to happen with other formats too)
2. Modify the file externally (by changing git branches, by formatting it with 'prettier', etc) or simply press F5

OBSERVED RESULT
Sometimes, the syntax highlighting will be reset and the text appears totally white. The syntax mode show at the bottom right corner is correct, but is not applied. I need to click that menu and select the language again. I haven't found correlations between this bug and other factors, it seems random.

EXPECTED RESULT
The file should reload and keep the original syntax highlighting.

Git commit 6314c0b9e62b17174ba8425a968a63d590e83d61 by Christoph Cullmann, on behalf of loh tar.

Pushed by cullmann into branch 'master'.

Ensure to set highlight on reload when file type was set by user

This change do essentially nothing else than before, we only call
updateFileType(..) direct and not by setMode() which allows bypassing
the blocking in updateFileType(..)
