Code Snippet

Repro Steps

This repros on Legacy and LSP notebook support. After reloading the window, the colors do not appear until I edit the file and trigger a completion as the GIF shows

Expected behavior

The colors should light up on reload

Logs

The following log entry shows up when I start typing: (43764) [BG(2)] getSemanticTokens full at c:\Users\judej\source\scratch\pd1\test.ipynb:pylance-notebook-cell:ch0000000 (1ms)

hmm. strange. We seem to be returning a response, but no color update is happening.

I only see this bug with pylanceLspNotebooksEnabled = true.

Not sure why full tokens is empty

@bschnurr, if you can repro this, could you try reproing with this extra logging that I created for Rich? https://github.com/debonte/pyrx/commit/e97106d778367d1835812ba9bb78d1bfe2f1aa33

The issue stopped reproing for him when I gave him this change and I've never been able to repro it.

This issue has been fixed in version 2022.8.51, which we've just released. You can find the changelog here: CHANGELOG.md
