Bug Description:

After the first time clicking on a Git diff marker in the gutter to show it (maybe even revert it), any further clicking on similar markers has no effect. No other Git diffs are shown.

Steps to Reproduce:

1. Edit text in some TypeScript files in a Git repository.
2. Click on a difference marker in the gutter to show the difference.
3. Revert or not, it doesn't matter. It's enough to bring up the difference viewer pop-up.
4. Now click on any other difference marker.
5. Observe that nothing happens.
