Column filter 'Select' mode to open on down arrow click

[JRiddick-Fisher]

Currently working with MRT V3 and noticed that when using the 'Select' column filter, the options don't expand open if you click on the little down arrow icon. This is especially odd since underline shows the focus animation of changing the bottom border to solid black to blue. The options only expand open when you click, maybe, 100px to the left of the arrow. It's also worth noting that I have the clearable option enabled.
