Clicking on the urlbar to focus it, should normally Select All, so its contents are ready to be replaced.
Unfortunately often this doesn't work and I end up inserting some text in the middle of the URL.
I found this is due to a few (1px, 2px) mousemove between mousedown and mouseup, that I may inadvertently do.
This is normally not a problem, but because the URL shifts when we insert or remove icons before it, we end up causing a selection change (the mouse moved by 1 px, the url moved by many pixels, so now 1-3 characters are selected).

Other browsers solved this by not shifting the url between focused and unfocused state, though that means we can only have a fixed amount of space for icons before the url, we cannot dynamically insert or remove icons then.
Possible solutions to evaluate:
1. don't collapse/uncollapse icons on focus change if mousedown. We can probably do this with a `mousedown` attribute and changing a few css rules. Icons would instead appear/disappear on mouseup
2. we could ignore small mousemove (less than half of a character) when passing from focused to unfocused... this may potentially prevent some wanted selection change, or not catch larger mousemove that users with accessibility problems may do
