[UX] Compare by content: current line is not marked, when focus in 2-lines area

[Flint]

If you work primarily from keyboard, you may find yourself in the following situation:
1. Open Compare by content.
2. Press Down several times to put focus on some line.
3. Press Ctrl+Tab to set focus into the 2-lines area.
4. Now you cannot see which pair of lines is chosen for comparison, because only selection is visible in the main panels, and it's still set on the first line. The compared lines are defined by the focus, but the focus border is not displayed.

Maybe TC should use the InactiveFocus-like feature here?

When you switch from a panel to another one, there are two lines identically marked as selection. You have to guess which line is active in comparison area.

You can see the line numbers in all 3 windows (as long as you don't scroll). It would be strange if the line suddenly got selected in edit mode.

But we do scroll. And the position of the comparison area stay unchanged when I click another line so I can't see new line numbers.

Besides, having to read the numbers and search for the same numbers in the panel is much more tedious, than just seeing any visual marking directly on the line.It could be a different background, or a light-grey border (so that it was different from the black focus border)…

I'm moving this to fixed bugs because I have added the function in the meantime.

There are still problems.
Steps to reproduce:
1. Click panels with displayed files to select lines for comparison. Both lines will be highglighted in the same way.
2. Click 2-lines area and observe changes. It will be highlighted a line number from the last active panel there. The same number in that panel now may be invisible - displayed in white-on-white. The 2-lines area is scrolled together with line numbers so now only one number stays visible. In some cases you can guess the missing number, but it's annoying.

Sorry, I do not understand your report. What exactly should be invisible in your screenshot?

All line numbers should be VISIBLE. They aren't, see the areas in red rectangles on the new screenshot:

1. Line selected in the top panel. You can see its number: 2871.
2. Line selected in the bottom panel. You can't see its number. In this case you have to guess that it's 548.
3. Both lines in 2-line area - there are NO visible line numbers when scrolling. You have to look for them in other places.

Usher,
Your screenshot link gives me an error.

You have to wait a moment while your browser executes megabytes of javascript code. I can see the picture in Firefox 52.9 and I don't think you are using any older browser. Maybe you should change adblock settings?

Usher,
This is what I am getting both in Firefox and in Vivaldi - https://postimg.cc/mhgWgBfB

Something seems to be blocked by your internet security suite or your internet provider. Try another link.

Usher,
Your second link works fine, thanks

That is the same problem I describe here: viewtopic.php?p=399688#p399688
