Webview: Fix broken fullscreen modals due to zero body height.

Supersedes PR #8536
Fixes #5211

JavaScript plugins such as Fotorama are broken when attempting use its fullscreen feature.

If there's an absolute HTML element with 100% height under <body>, its height is 0 when rendered in the Android WebView.

This commit fixes it.
Closes #8830
