This is the collected backtrace, missing functionality in WKTR:

fast/events/touch/force-press-event.html

Moved out of iphone7 folder by 254521@main. It's crashing at the same site.

Also happening on the following when attempting to implement event-timing:

- imported/w3c/web-platform-tests/event-timing/TapToStopFling.html
- imported/w3c/web-platform-tests/event-timing/interaction-count-tap.html

[Franco Vieira]

Crash logs for the event-timing runs can be found here: https://ews-build.webkit.org/#/builders/34/builds/85287

They look a bit different for me:

STDERR: SHOULD NEVER BE REACHED
STDERR: /app/webkit/Tools/TestRunnerShared/UIScriptContext/UIScriptController.h(73) : void WTR::UIScriptController::notImplemented() const
STDERR: 1   0x55fecf8d9cc3 WTR::UIScriptController::notImplemented() const [clone .isra.0]
STDERR: 2   0x55fecf8da2e9 ???

All ports skips the tests after 280139@main. But, only WPE is running the tests and crashing. I'm going to skip them for WPE.
