1534562 - setPointerCapture on element in shadow DOM produces InvalidStateError

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[luki.schaer]

Attachment: minimal reproduction example

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.36

Steps to reproduce:

• Open the attached .html file in Firefox.
• Click the red square to trigger the onpointerdown function attached to the innerDiv
  -> This triggers the function that calls setPointerCapture

Actual results:

An InvalidStateError is produced and logged to the console (An attempt was made to use an object that is not, or is no longer, usable)

Expected results:

The function call should be allowed and not produce this error, as it seems to be allowed according to this specification[1]: there is no PointerLock, and the innerDiv is connected.

FWIW, this is a change in pointer events v2. We seem to follow v1 here.
