1038002 - Holding your finger down and then trying to pan gets stuck until the next touch

Status: RESOLVED DUPLICATE of bug 1009733

(Core :: Panning and Zooming, defect)

Description

[Doug Sherk (:drs) (inactive)]

Attachment: Reduced test case

STR:

1) Open attached test case.
2) Place finger down for a few hundred ms.
3) Try panning.

Expected: Document pans.
Actual: Document is locked in place.

I think this behavior makes sense if the contextmenu event is preventDefaulted, but otherwise the document should always be pannable. There are additional side-effects to this behavior. For example, the box in the test case goes red when active, but doesn't get set inactive until the user places a finger down again. This is causing problems in Gaia, such as in bug 1033937.

Just to clarify, based on what you showed me in person: "getting stuck" doesn't mean that *subsequent* touch blocks are ignored, only that *this* touch block (which began with the long tap) doesn't result in panning, right?

Yes.

I believe my patch on bug 1009733 fixes this. When I tested locally it also fixed the :active highlight issue, but marking this as blocking bug 1014322 anyway to make sure we end up being consistent with other CSS :active behaviour.
