| 8 This is a regression test against a double unregistration of a touch action |
| 9 event handler on a <br> element. When the document finishes loading and is |
| 10 attached to the view, all of its RenderObjects are destroyed and recreated. If |
| 11 a RenderObject had a touch action associated with it, it will need to remove |
| 12 the fake event handler it registered for it in the EventHandlerRegistry. |
| 13 However, when the document gets detached, all of the event handlers within it |
| 14 are automatically unregistered. When the RenderObject tries to unregister its |
| 15 own handler after the fact, it is no longer there and we hit an assertion |
| 16 failure. |
| 17 |
| 18 Note that this test doesn't use js-test.js because it also inadvertedly |
| 19 triggers the same bug by appending <br> elements to the document. |
| 20 |
| 21 The test passes if it doesn't trigger an assertion failure in a debug build. |
