iFrames on a panel do not receive input

[JaredMonkey]

To repro, put any page as an iFrame in a panel and try and touch. Scrolling, or any click or input events don't seem to work on the iframe.

May be an issue in CEF? https://bitbucket.org/chromiumembedded/cef/issues/2789/osr-branch-3904-iframes-doesnt-handle

In the discussions in the CEF issue linked above folks mentioned using --disable-site-isolation-trials

If I set this as a launch option, I'm able to get input in an iframe. Using this workaround for the moment.
