Cannot leave comments on hunks in large diffs

[aursulis]

• Extension version: v0.100.3
• VSCode Version: 1.95.3 (system setup)
• OS: Windows_NT x64 10.0.19045
• Repository Clone Configuration (single repository/fork of an upstream repository): single
• Github Product (Github.com/Github Enterprise version x.x.x): Github Enterprise Server 3.12.9

Steps to Reproduce:

Checkout a pull request that contains large diffs (ones which Github renders as "Load diff / Large diffs are not rendered by default"). Open that large diff as a side-by-side view:

• the line in the gutter showing where you can leave comments is not displayed
• hovering over the gutter on changed lines does not display the comment button
• however, comments made via the Github UI are visible

I don't have any PR to hand to demonstrate as I'm using this with a Github Enterprise Server, but would be happy to make a fake one on GH if needed.

I conveniently just made #6536, and there's a large diff file there.

I'm not able to repro the issue. Do you see the issue with that file?

[aursulis]

No, indeed I can't see the issue with that file. I've made aursulis/test-repo-1#1 which reproduces it for me.

So maybe something to do with the number of hunks, or lines changed? For reference, the (non-contrived) PR I encountered this on had 171 1-line changes in a file. 35 spaced out by 12 lines, and the rest separated by 2 or 4 lines
