Incorrect behavior on collapsed lines

[Aliph0th]

As you can see in the picture above, if you collapse the lines of code, the relative numbers are not displayed further

At this point,
The only way I can think of to fix this bug is to make it slower than it is now.
For example, scan DOM and rewrite CSS for each folded range.

I'll leave this bug alone for a while.
Once I come up with a reasonably fast solution, I'll get to work.
