Toggling file node in Comments view focuses comment

[joyceerhl]

Testing #194012

1. Checkout Allow hiding of launcher on Run and Debug title bar when debugging #193812
2. Open comments view
3. Have debug.contribution.ts open and scrolled to the top of the file
4. Hit enter in the debug.contribution.ts node
5. 🐛 I get scrolled to the first comment

This also happens if I expand the node after collapsing it, which I found a bit surprising, as I didn't hit enter on a specific comment, just the file node

There are a couple problems here:

• We should only expand/collapse the file node when the twisty is clicked/entered (we should have both an action and an expand/collapse with the file is clicked/entered)
• We should just open the file and not scroll to a comment when the file node is clicked/entered.

Actually, since you're opening the file from the Comments view, it makes sense to reveal the first comment. I'm just going to fix the expand/collapse + action issue.

I just verified this by making sure that clicking on the node doesn't expand/collapse the node (only the twistie can). Please lmk if that's sufficient!

That is sufficient!
