Bug: Bottom Gap appears randomly
Hi,
it seems like an essential thing broke since iOS 16.4 (seems like Android is not affected): The Modal Sheet does not start at the bottom. I could not find a way to re-produce it exactly, but it happens often (and randomly). I thought it was a problem in my app, but I just saw that it happens in the Apple Music demo (https://temzasse.github.io/react-modal-sheet/) too.
Maybe you have to open the Modal a couple times, but it will happen definitely. Here is a Screen Recording:

It's a pretty small gap here, but it can be quite big.
This happens on Chrome and Safari. Tested multiple devices, happens everywhere.
I have found a way to reproduce it. You just need to scroll a couple pixels down from the very top of the page (and open a modal then). Seems like that it just happens when scrolling 1 to 30px. After 30px it works fine. @Temzasse why does it add a negative margin-top to the body when opening the modal? May be related to this bug...
Hi 👋🏻 Thanks for reporting this!
There is probably a bug in the sheet height calculation related to the dynamic browser viewport height. I'll try to find time and see if we can use the new dvh, lvh, svh units to fix this issue 🕵🏻
Hi @Temzasse, may I know if there is an update on this particular bug? Similar to adshrc, I can't replicate this reliably but it does happens now and then.
No updates unfortunately. A proper reproduction would help a lot to debug this issue. Without a repro it's just a guessing game 😅
