Log Message:
-----------
Occasional crash in WKMouseDeviceObserver.connectedDeviceCount.setter due to
precondition violation
https://bugs.webkit.org/show_bug.cgi?id=295342
rdar://154860259
Reviewed by Aditya Keerthi.
This crash happens due to a violation of the precondition asserting that the
number of connected devices
is >= 0. This is a perfectly valid precondition, since it doesn't make sense
that there could be a _negative_
amount of connected devices.
This implies that there is some underlying issue in how the notifications are
published. To workaround this
and be more resliant, access the array of connected devices directly and use
its count, instead of manually
incrementing and decrementing.
