Bug 1784847 - Disable the breakpoint tests of composition events until bug 1466596 or bug 1690827 is fixed r=bomsy

I think that fixing the crash bug requires a big design change to manage
delayed composition commit requests from a remote process and I don't have
much time to work on it but the intermittent failure frequency has spiked up.
Therefore, we need temporarily to comment out the block for now.
