Task POI navigation UX is confusing

[sbatten]

Testing #153365

When I use cmd+up/down to navigate between POIs in task output, the blue box renders for a second on the item I have selected, but then disappears. I didn't understand what was happening to the focus border.

that is by design.

This has come up before, @misolori I think you had an idea to improve this?

[miguelsolorio]

I had the same experience in #145801 where I was on a slow machine. I think I had suggested just using a line on the side (like our activity bar) that remains until your focus changes:

To the left of the command decorations?

I like how visible the outline is when jumping between commands, so we could keep that as is and just also show the persistent line?

[miguelsolorio]

yea I'd be open to trying that out, I think using both might be a bit overkill but just having the single line can also be hard to notice.
