Issue: Inline diff-view sometimes hides deleted or changed lines
Labels: bug,verification-found,diff-editor

Type: <b>Bug</b>

1. Select a file under source control (only tested with git).
2. modify the file.
3. select Source Control Panel
4. Observe file is listed under "Changes"
5. select file.
6. In the diff-viewer, select the upper "three-dots" button and ensure "inline view" is unchecked.
7. observe one side of the screen has the old version in red shading
8. and the other has the change in green
9. check "inline-view"
10. observe the difference is now shown as a single editor with both red and green areas.

Expected result:
always see both old and new values

Actual result:
Sometimes the old value is only highlighed in the mini map, and not shown in the actual text.  
This is intermittent and reloading the VS Code window seems to resolve this problem, but have not found a way to reset the view except by reloading VSC.
