Focus sticky scroll is not preserved when sticky lines disappear and reapper

[dbaeumer]

Testing #177642

• have a couple of lines in sticky scroll
• Focus sticky scroll
• scroll inside the file to a place that sticky scroll lines disappear
• scroll to a place that has sticky scroll lines again

Observe: focus is lost. I would have expected that focus is kept.

Closing the issue since this is actually by design. Still I would have expected otherwise.

I am actually reopening it since I think the behavior is not good when scrolling using the scroll bar / minimap

[dbaeumer]

Do the following:

• focus sticky scroll
• use the minimap to scroll to the top of the file whithout releasing the mouse
• Observe: sticky scroll disappears and focus is gone
• Scroll into the file again
• Observe: sticky scroll apprears without focus.

I would have expected in this case that the focus is preserved since I never released the mouse button.
