Hello!

Currently OnDraggableRegionsChanged is only called once on the page load. If later JS modifies CSS attributes, moves, creates, deletes DOM elements, the callback is not called again and the draggable regions are not re-calculated.

It prevents some scenarios when a dynamic control elements appear on the draggable header.

Is is possible to fix this problem?

What OS and CEF version? Looks to me this might be an issue in upstream. You could check how it behaves in Electron (and maybe check its issue tracker as well)

windows as well as linux. CEF 3.3359.1774
