The file \layouts\joomla\toolbar\dropdown.php has several hard coded strings that should be translatable
Note it is not just as simple as creating a new string for the text that is there because the text is wrong

Oh okay, yes, it's not translated and even not displayed.
I would suggest to remove these whole unnecessary line including associaded CSS
some lines above is a aria-label:
What would you suggest to have as text brian?
"Toggle Dropdown" should better be placed as title attribute for the button itself ;)
I think that "Toggle Dropdown" is pretty useless as aria label
One question: Do we have a prefered language key prefix for layouts?
I think this text has to be set by the calling component.

I can't find an usage of this layout in core. Can you point me in a direction?
