With the addition of distributions to the Atlas view options, the view button is inappropriately changing sizes on hover.
Hovering or clicking on the view button should show the view options without changing the size or position of the view button itself.
When hovering or clicking on the view button, the view button is either moving or shrinking such that the right edge of the button moves (it might be the button is not shrinking, but just moving to the left). See attached GIF of behavior.
