Clicking on the edge of the SCM input box causes it to lose focus

I don't know why, but I often seem to click in a space in the input box that causes the focus to be lost.

I've added a click logger in devtools:

e = window.addEventListener('click', e => console.log(e.target), true)

Which tells me it's view-lines monaco-mouse-cursor-text that's being hit. @alexdima shouldn't the editor take that as a focus intention? Here's what I found when debugging, notice all the false values, when the editor is trying to figure out what's hit:

When clicking right in the middle of the editor content area I get targetIsContent as true. But when hitting view-lines, everything is declared as false.
