If height of element is changed in moment when header gets "is-sticky" class, animation has glitches

If height of element is changed in moment when header gets "is-sticky" class, animation has glitches. For example I have larger logo and after "is-sticky" state I want to replace it with smaller one. Around that scroll spot, "is-sticky" class gets gone and gets back several times in few milliseconds because of changing of sticked header height.

Having the same issue. Causes the header to flash multiple times in and out of it's collapsed state.
