"12 References" text jumps up and down by a few pixels whenever I'm typing

Issue Description

References text jumps up and down by a few pixels whenever I’m typing in text.

Somewhat related maybe to https://github.com/OmniSharp/omnisharp-vscode/issues/1173 but not entirely. It’s not clear to me what exactly #1173 talks about since there’s no Gif/animation showing the undesired behaviour.

Steps to Reproduce

Unsure as to when this behaviour occurs. Not all of the References are jumpy - doesn’t seem to be a trivial relationship. It’s not necessarily the References closest to the cursor, References inside classes seem to be more jumpy than references outside of it.

Expected Behavior

The References text doesn’t jump up and down.

Actual Behavior

The References text jumps up and down.

I have created https://github.com/microsoft/vscode/issues/113384 to continue the investigation on our side

It’s occurring again, after hibernation - that could be a clue.

The top value does change. I did a “break on attribute changed” and it’s triggered by something to do with “Light Bulb” in codeAction. See screenshot. There are two changes, one to move it up by a pixel, one to move it down. The movement up is probably the culprit.
