Thanks for the report. I recently noticed this myself and started working on the blue branch. My solution is the same as yours in #70 but I did not manage to write a test that works consistently for different neovim versions. They changed something in the filetype handling that make the tests fail on some versions of neovim.

I have given up constructing a reliable test that works on 0.6 and 0.7.1 & 0.7.2. I will have come to that problem later or increase the minimum version requirement just for the tests.

But the fix you need is now in main.
