reproducible blinking error

A div with long content blinks when you scroll and switching position "fixed/relative" by clicking the card 


What steps will reproduce the problem?
(1) Scroll the page to the end
(2) click on the card
(3) click again on the card

What is the expected result?
The card should be positioned without any blinks when changing CSS position property and changing scroll position

What is the actual result?
The floating card is blinking

Any additional information (anything else which may help us debug the
issue)?
