HTML content clipping

HTML content clipping

In long HTML content, it clips the content section from the bottom and does not show the whole content.

It seems like this might a known issue. In README.md, it states:

If you are trying to display very large content, it may not be displayed.

This might be an underlying problem with the WebKit rendering engine. You could try using the latest commit of PR #64 and see if the SwiftUI-native WebView still has this issue.

Fixed in #78.

The height was measured once in window.onload using offsetHeight, so any layout that settled after that point was never reported back to SwiftUI and the bottom of the document was cut off. Fractional layout heights were also truncated rather than rounded up, which cost another pixel.

The container is now watched with a ResizeObserver, and the reported height is ceil(max(scrollHeight, getBoundingClientRect().height)). Late images, web fonts, rotation and Dynamic Type changes all trigger a re-measure now.

Note that the README caveat about very large documents is a separate WebKit tiling limit, not this bug. If you still see clipping on the next release, please reopen with the approximate content size.
