The chrome browser crashes in mash when you try to do something that accesses the clipboard contents (like paste or long touching on Chrome OS).

Here is the stack trace I get from hitting <C-v> into the Chrome omnibox an Oxygen build.

[15622:15622:0622/141430:FATAL:sync_call_restrictions.cc(71)] Mojo sync calls are not allowed in this process because they can lead to jank and deadlock. If you must make an exception, please see SyncCallRestrictions::ScopedAllowSyncCall and consult mojo/OWNERS.
