Shop Switcher Opens Off-Screen

[pmn4]

It seems that once you get over n Shops, the Shop Switcher becomes too long, and is positioned above the label. (I'm not positive what n needs to be to make this happen, but I have 24 currently)

Expected behavior

The drop-down to appear on the screen (and be scrollable, I guess?)

Actual behavior

It appears above the selector, but since that is located in the navbar, it is rendered off screen, above the top of the page (see screenshot).

Steps to reproduce the behavior

Create 24 Shops on a 13" MPB (that may not be the exact number, but that is what I have now and notice the issue)

Versions

Sounds like an issue with the dropdown component - probably not specific to the shop switcher itself?
