Themes Dropdown, arrow prevents input from receiving focus

[Sapo84]

Pretty much what's written in the title, if you click on the arrow the input will not receive focus and the options are not shown.
It's pretty strange that the dropdown arrow does nothing at all when I would imagine a user will click on it to open the dropdown (well, I do, it's very possible I'm the strange one).
document.getElementsByClassName("arrd")[0].addEventListener("click", function() {document.getElementsByClassName("dropbtn")[0].focus();});
Something like that solves the problem on my end.

I also think it would be nicer for the arrow span to cover the right part of the dropdown without a gap, currently there are 5 pixels where the cursor gets back to text (and clicking on them also opens the dropdown since the click focuses on the input)

I had rewritten drop-down a while back to fix this but never got around to push because we got side-tracked with communication between UI Elements. I'll do a quick fix for this in couple of days.
