VisualViewport resize event not fired on iOS26 with WebView

[wilfrem]

Problem

• VisualViewport resize event not fired when keyboard open

Condition

• iOS26
• in WebView (Safari is not affected)
• launching an app with WebView, return to the home screen, wait 10 seconds, and then reopen this app.

Workaround

• visualViewport's width and height return the correct value, so periodically checking may solve it.

wow ... why is this still needed these days? 😱

We fork and customize this version and use it to recalculate the layout when the keyboard is opened or closed.
So we're not using this library as is.
We're reporting the issue we encountered this time because it could also occur with the original version.
However, since the root cause lies in iOS 26's WebView, we're not sure whether this issue should be addressed by this library.

I've found this which should be the solution these days: https://medium.com/@TusharKanjariya/why-100vh-breaks-on-mobile-and-what-to-use-instead-a4e65cb2797f
