Extension periodically refreshes the file under review, resetting the view position

[RikkiGibson]

Description

1. Install both GitHub Pull Requests (v0.50.0) and https://marketplace.visualstudio.com/items?itemName=eamodio.gitlens (v12.2.2).
2. Open a pull request in the extension and begin reviewing a file
3. Proceed with review for about 1-2 minutes

Expected behavior: editor view position is only affected by user actions (e.g. navigation commands, scrolling)
Actual behavior: editor view position is periodically reset, disrupting the review.

Note that this behavior only occurs when both the GitLens and GitHub extensions are enabled. When I disable the GitLens extension, the bad behavior stops. I am not sure which extension is to "blame" in this scenario, so I'm taking the liberty of filing a bug both here and at gitkraken/vscode-gitlens#2259.

Logs, Screenshots, Screen Captures, etc

This recording roughly shows the bad behavior, which occurs once every 1-2 minutes. Note that several different activity indicators are popping up in the left sidebar before the editor tab goes blank and refreshes.

I haven't yet been able to reproduce this issue. I'll keep an eye out for it.

And now I was just able to repro it.

[eamodio]

@alexr00 is this a GHPR issue?

[alexr00]

@eamodio I found a GHPR issue that caused it. I don't know why the issue would only repro with Gitlens. I would assume that was a fluke as it didn't occur 100% of the time for me.

Awesome thank you!

Do you we know when this fix is going available in the insiders build?

As it also appears reset comments, which is a bit of a PITA :-)

[alexr00]

@jpspringall the fix has been in the pre-release build of the extension (which requires that you use VS Code Insiders) for about 2 weeks.
