Try to add position:static on body.

getPos util function from TinyMCE won't use getBoudingClientRect to get trigger element's position if the body isn't statically positionned (because left/top properties values applied on tooltip, which is a body child, wouldn't be accurate if body had margins for instance).

But using getBoudingClientRect is the only way to get the right element's coordinates when there is some parent on its own transformation layer.

Ok, I think I know why this hasn't been fixed as its possibly an edge case scenario. If I run either Chrome or Edge browsers on my primary monitor (I have two), then it works as expected. However, if I use it on my secondary monitor it doesn't work and reproduces the original reported problem. So I'm not sure if that's a bug with the browsers or the product. I can repro this using the feature sample here:
