Details 
When we pull down the notification bar, sometimes it got stuck in the middle. Once stuck, it is neither going up or down.

Steps to reproduce:
1. Open Browser
2. Browse for any websites.
3. There are two ways to reproduce this issue
  a. While loading the web page, pull down the notification bar slightly.     
     Reproducibility is 5/5
  b. After loading the webpage, pull down the notification bar slightly. 
     Reproducibility is 3/5
[Blocking Requested - why for this release]:
Blocks: CAF-v2.0-FC-metabug
blocking-b2g: --- → 2.0?
Component: Gaia::System::Window Mgmt → Gaia::System
Can we please have the exact STR and video to help with progressing here?
Flags: needinfo?(poojas)
Chris, could this be a regression from your animation patch?
Flags: needinfo?(chrislord.net)
blocking-b2g: 2.0? → 2.0+
STR is similar as before
1. Open Browser

2. Browse for any websites.

3. While loading the web page, pull down the notification bar slightly.
   Try pulling it multiple times. After few trail its stuck in half way

QA Wanted - can we do branch checks here to see if it's a regression?

I guess it's possible, but I wouldn't have expected it. I'll wait for the regression window to confirm, I can't imagine it's too hard to fix either way (famous last words...)

The bug in question is bug 1038185.
Can we get a logcat as well?
Assigning to chris for now. Lets re-assign if we find a better owner after we get a regression window.

Is this actually blocking CAF? I don't see a CR or caf priority in the whiteboard.

Oops, yes still it will have a CR

Weird, I can reproduce this in 2.0 but it's strange to me that it doesn't happen in 2.1 - I guess the uplifted patch conflicted with some behaviour that was changed in the interim? Looking into it.

This is happening because we're not preventing default on the touch-start, and presumably something else with higher priority wrt the event chain is swallowing the subsequent events.

I'm not sure why we don't see this in 2.1, possibly because the browser has changed behaviour or some other reason, but we probably should just always preventDefault on these events - I'm not sure why we don't.

I think we can simplify this code a bit, it seems to be doing a lot of seemingly redundant things.
Ok, this is weird, even having fixed that, I'm still getting strange behaviour... Starting to think that perhaps this is a platform bug? I'll test with master Gecko after a bit more digging.
This issue seems to be caused by Bug 1021512.  Seems related to what Chris is talking about.

Can confirm that this isn't a Gecko bug... Looking at bug 1021512 I'm not sure why that would cause this, unless the touchcancel we synthesise ends up cancelling our touch event block?

n?etienne for comment, I'm kinda stumped on this right now. I'll carry on looking though.

I had a thought about this last night, is the browser still sharing the system process like it used to? Because if so, this behaviour makes some sense and we just need to special-case the browser in the code added in bug 1021512.
We are special casing [1]... |config.oop| should be false for the browser.

Ah! Not on 2.0.

Sorry for the noise, I'm pretty sure we just need to uplift bug 1027035.
And probably mark this one as a dupe.

Cheers!
