[REG 5.15] D-Bus assertion failure - video content

Since the fix for QTBUG-85475 was applied, my WebEngine widgets  browser is crashing when any media begins to play.

My suspicion is that it has to do with this commit: https://code.qt.io/cgit/qt/qtwebengine-chromium.git/commit/?h=80-based&id=946516b70549629dc9108473a9c34c14a36126ab 

This error message is printed to the console as the application crashes-

dbus[11826]: arguments to dbus_bus_request_name() were incorrect, assertion "_dbus_check_is_valid_bus_name (name)" 
failed in file dbus-bus.c line 1122.
