Mouseklick not working anymore with 2.46.x using ENABLE_WPE_PLATFORM

[ZmRZjFuDsDiR4qi5801F]

Hello,

we're using a snap based on https://snapcraft.io/wpe-webkit-mir-kiosk, and updated to webkit 2.46.x (https://wpewebkit.org/release/)
Since wpewebkit2.44.x the mouse click event does not work anymore. I found some changes mentioned in

https://github.com/WebPlatformForEmbedded/WPEWebKit/blob/wpe-2.46/Source/WebKit/wpe/NEWS:

"Add a ENABLE_WPE_PLATFORM build option to CMake. This is disabled by
default because the WPEPlatform API is in development and provided as
part of the 2.46.x releases as a preview feature."

Because I'm not sure if the feature is temporarily not available or has to be enabled explicitly with some options, please let me know how to get this working again. We appreciate any help.

https://github.com/WebKit/WebKit/blob/main/Source/cmake/OptionsWPE.cmake:

if (ENABLE_WEBDRIVER)
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_KEYBOARD_INTERACTIONS ON)
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_MOUSE_INTERACTIONS ON)
if (ENABLE_WPE_PLATFORM)
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_TOUCH_INTERACTIONS ON)
else ()
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_TOUCH_INTERACTIONS OFF)
endif ()
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_WHEEL_INTERACTIONS ON)
endif ()
