Philip Jägenstedt b42c30ab12 Bug 1580460 [wpt PR 18992] - [fullscreen] wrap event listener callback in t.step_func, a=testonly
Automatic update from web-platform-tests
[fullscreen] wrap event listener callback in `t.step_func` (#18992)

This is to avoid a harness error if `trans.requestFullscreen()` is not supported:
