Selection not cleared in editor

[faerot]

Sometimes when you click between the edges of the line, when mouse press happens on one line and mouse release on another line, you get this:

One line is selected, another is just visual artifact, i.e. if pressed Ctrl+D to delete selected block, you get:

The "selection" clears only after that line is redrawn.
Not that I use mouse a lot in editor, it mostly happens when tring to re-focus back to far2l window, which is annoying.

Correction: it is not just visual artifact, this is actual selection part, because when typing over remaining selected block it wipes that block.
