bug(dropdowns): combobox triggers layout reflow onUpdate and breaks animation

[kspeyanski]

Currently, internal layout reflow is triggered on componentDidUpdate method of the ComboBox, which causes a layout reflow during ongoing animation. Can be observed in the following stacklitz example: https://stackblitz.com/edit/react-8mxlqb?file=CompTwo.js

Further investigation is required to confirm if this can be fixed in the ComboBox or in the Animation.

@kspeyanski Any status update? I have tried the example, but I couldn`t observe any obvious problems with it. Is it possible that it was browser related?
