Collapsible flickering when toggled too fast

[marceloadsj]

First of all, great project everyone, congratz. 😄

Steps to reproduce the issue:

• Go to https://hsds.helpscout.com/?path=/story/utilities-ui-interactive-collapsible--default-story
• Click on Toggle button twice (fast)
• Note that the closing animation will jump and flicker

I fixed that issue on this commit (my fork): https://github.com/marceloadsj/hsds-react/commit/c8c0e747fb0a60e1db40d816ac010689ab6404d1
