Multi-line tab suggestions in Notepads break text selection

[theio]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Basically, the title. Sometimes when cursor suggests multiline autocomplete you can no longer select text using your mouse. In the screen, no matter where you click, you can’t hold down left button to select text, it just never happens. Like, if I click anywhere and start moving mouse, it doesn’t select text. Worth mentioning, that’s a pretty old bug at this point.

Steps to Reproduce

Sometimes happens in jupyter notepad cells when multiline tab autocomplete suggestion is being made

Expected Behavior

Well, you should still be able to select text?..

Sometimes - I can sometimes use Cursor

Hey, thanks for the report. To reproduce, we need a bit more context.

Could you please:

• record a short video showing when the multiline suggestion appears and that mouse selection doesn’t work
• say whether the same happens in a regular .py file outside notebooks
• check if selection comes back after pressing ESC to hide the suggestion, and whether keyboard selection works (Shift+arrows)
• open Help > Toggle Developer Tools > Console and share the errors at the moment of the bug
• close Cursor and launch from the terminal: cursor --disable-extensions, then check if the issue persists

Once we have the data/video and stable repro steps, I’ll pass it to the team.
