Theme selector opens at strange position on mobile #408
Description
Describe the bug
On a mobile device, when tapping the icon to switch dark/light mode, the dropdown appears way too much to the right. At first, I thought it didn't work at all. Took me a while to realize it popped open at the right. Because when tapping on the icon with my right hand, my hand covers the location where the dropdown opens, so I didn't notice the UI change.
