git extension: stale and ignored resources appear under Staged Changes

[mattseddon]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.60.1
• OS Version: Darwin x64 20.6.0

Steps to Reproduce:

1. Run a machine learning experiment with the workspace open.
2. 5k ignored files will appear under "staged changes" (files to do not appear under git status -z -u).
3. Stage any file through the UI.
4. Stale files disappear from the "Staged Changes" resource list.

I think that potentially the @throttle decorator here is the cause of the stale data.

The way that the experiment run works is:

1. a temporary branch is created
2. the experiment is run against that branch
3. the results are returned to the workspace
4. the temporary branch is removed

This is what the terminal looks like during the experiment 👇🏻

~/example-dvc-experiments main +2 ❯                                                                3.0.0 16:12:0

Is there anything that can be done to work around this issue?
Please let me know if you need any more context or information.
