jquery__event_type_pointerpressrelease: pointerpress event is triggered twice on each mousedown in IE10.

[dfilatov]

$(document).on('pointerpress', function() {
    console.log('pointerpress');
});

@dfilatov I've added a test for pointerpressrelease in the issues/505@v2 branch. Could you check it in your IE version, because I can't reproduce this issue.

› git co issues/505@v2
› bem server 
› open desktop.tests/jquery__event_type_pointerpressrelease/simple/simple.html

See query__event_type_pointerpressrelease.tests/simple.blocks/example/example.js for code.

There was a bug in our .bem/make.js / bem-pr configuration, so desktop.tests/'s blocks were included twice :)

@dfilatov could you check this https://github.com/narqo/test-pointerevents? I'm not sure, but it looks like doc.on('pointerrelease', <handler>) has strange behavior in any browser there.

On <button> press, I get two messages in console:

› press
› release

while in my opinion there should be only first one.

Actually I understand why this is happening, but I don't understand is it correct?

[dfilatov]

Yes, it's a very strange behaviour.
But, when I replaced pointerpress by mousedown and pointerrelease by mouseup -- all became to work as it was expected. I thought that pointerpress/pointerrelease events are transparent wrappers around mousedown/mouseup events for desktops, but ... (

There is a bug in @deepsweet's jquery-pointerpressrelease.js implementation, which, I think, was fixed in bem-core, but haven't been backported to upstream.

I'll try to dig the original issue more deeply
