Public bug reported:

When a webview is hidden we hold on to the frontbuffer until it is made
visible again. Instead of doing this, we should consider evicting all
buffers for hidden views in order to free resources. A tradeoff of this
would be small delay when making a hidden view visible again.

On Android, Chrome evicts frames for all hidden views. On destkop, it
doesn't evict all of them but does cap the number based on available
memory
