When rendering 2 'div' components with 'display:flex' placed on top of each other, the preceding one sometimes comes up. The 'position:absolute' has been set and the second 'div' component is being generated after the first one. However, when inspecting the iOS webview in Safari, I enable-disable the 'display:flex' property, everything starts working again. This is possibly a bug in the layout engine.
I tried the same process in iOS 16.4 and there are no issues at all.
