[A11Y] - Missing aria label on overflow menu toggle

[josephcoombes]

Bug Description
This button (3 dots) doesn't have any text in it, so when a screenreader is reading it, it only speaks the word "Button". Users with screenreaders will have no idea what this button does.

Steps to Reproduce
If you have a screenreader installed, you can navigate to this item and should notice that the screenreader says "button".

You can install a screenreader here: https://chrome.google.com/webstore/detail/screen-reader/kgejglhpjiefppelpmljglcjbhoiplfn/related?hl=en or enable on your OS.

Expected Behavior
This should have a descriptive label aria-label. At the very least, it should say something like "Menu", but as clear and descriptive as possible is ideal.
