Scroll position jumps about 3 lines when closing Quick Open via click

[peterflynn]

This looks like a case of #9037 that wasn't fixed:

1. Open a file and scroll somewhere to the middle
2. Press Ctrl-Shift-O
3. Click inside the editor

Result: editor scroll position moves down ~3 lines.
Expected: scroll position unchanged from step 1.

Or...

1. Press Ctrl-T
2. Type to filter down to a function name
3. Click inside the editor

Result: editor scroll position jumps down ~3 lines from where it was after step 2 (most noticeable if you watch the bottom edge of the editor).
Expected: editor scroll position doesn't change after step 2.

Both are regressions in 0.44, so flagging for 0.45.

seems like a less common case.

After digging into this more in pull request #9624, the number of cases makes this fix and testing complicated enough that I think this should wait until after 1.0.

it's also Low-priority so I agree it should wait. This code is pretty gnarly
