Switching inline on or off requires IDE restart

[OndrejSpanel]

Describe the bug

When I switch to or from inline highlighting, the IDE needs to be restarted for the option to apply.

To Reproduce

1. Switch from Background to Inline and press OK (I do this in Scala sources).

Expected Behavior

• background will no longer be highlighted
• colored icon will appear

What happens instead

• background is not highlighted
• colored icon will not appear
• you need to restart the IDE for this type of change to be applied

You don't need to restart, just close the current tab and reopen it and it should work.

I'm aware of this issue, but this is because the inline highlighting works differently than the other styles. But I think there has to be a solution somewhere. I'll keep this in the backlog.

Perhaps some event could be sent to the tab so that it redraws itself completely?
