Show inline scrolling jumps

[Kohina]

The show inline feature is very useful but I have the issues that if I try to go up or down a few rows in the inline window it jumps to a different place in the log and not where the line that was selected is.

That is, press a row and show inline, click to go up or down a few rows and the selection will jump away from the selected row.

Related (or even the cause): Pressing cursor down on the last visible row in the top pane while "Show inline" is active will set the focus to the inline view control, allowing me to resize it using the cursor keys. Pressing page down multiple times exhibits a similar focusing behavior, also focusing part of the inline view.
