Created attachment 404145 [details] 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)?
