       Edge: 14.14300 OK

What steps will reproduce the problem?
(1) Load the page
(2) Resize the window to be as small as possible
(3) Make the window large again and repeat step 2 several times

What is the expected result?

The dot should always stay in the middle of the browser window, both vertically and horizontally.

What happens instead?

The dot sometimes goes too much to the lower right corner and sometimes even disappears outside the browser window.

Please provide any additional information below. Attach a screenshot if
possible.

Page reload fixes this issue immediately and resizing the window slower reduces the chance of incorrect behaviour, which would point to a possible race condition. The small border is only there to show that the container gets resized correctly, according to our tests container size or container border is not relevant to the rendering bug.
