osr : Browser not correctly refreshing on Resize

The issue comes from upstream CEF, but could likely be patched here too: https://github.com/chromiumembedded/cef/issues/3826

When the OSR and the browser is resized, the size is not updated right and also sometimes gets stuck with the wrong size.

No repository file or test is identified in the report. Start by reading the linked CEF issue and its recommended fix, then trace JCEF's OSR resize handling; done means the browser size updates correctly during resizing and does not remain stuck at an incorrect size.
