===Tests===
One or more tests have to deal with switching the lock between multiple elements, and the [[Changes to Fullscreen Unlock|spec is changing]] on that front.

Example actions include:# '''DELETED'''# '''FIXED''' Other actions are also acceptable where appropriate.Once fixed, please pull request to rhung's [https://github.com/rhung/mozilla-central/tree/mouselock-tests/dom/tests/mochitest/mouselockrhung's mouselock-tests] branch and indicate that you've done so in the pull requested column.

(this may also include the scenario where there is an iframe in the parent element)# A Test to check that repeated move of the mouse to a certain direction that will exceed the screen size does not break the mouselock (this may conflict with file_movementXY.html and we may need to add more test cases) ====Changes To Be Applied To Submitted Tests[Deprecated]====
The following table is used to maintain a small note on the task for each test. It will include note from the review by Mozilla and issue we overlooked.

====Remaining Test Reviews[Deprecated]====
