Test Description:
This test checks if lostpointercapture is handled asynchronously and prior to all subsequent events.
Complete the following actions:
< ol >
2016-12-12 03:21:29 +00:00
< li > Press and hold left mouse button over "Set Capture" button and move a little. "gotpointercapture" should be logged inside of the black rectangle
2016-08-01 07:41:42 +00:00
< li > "lostpointercapture" should be logged inside of the black rectangle after pointerup
2015-03-31 05:02:00 +00:00
< / ol >
< / h4 >
Test passes if lostpointercapture is dispatched after releasing the mouse button and before any additional pointer events.
