Description
It looks like WebEngine hard assumes to be running on platform xcb. It does unconditional checks into X11-specific code and asserts.
Output from running minimal example:
sing Wayland-EGL [0819/101851:ERROR:resource_bundle.cc(720)] Failed to load /usr/share/qt5/resources/qtwebengine_devtools_resources.pak Some features may not be available.

[0819/101851:ERROR:resource_bundle.cc(720)] Failed to load /usr/share/qt5/resources/qtwebengine_devtools_resources.pak Some features may not be available.

[0819/101852:ERROR:webgraphicscontext3d_command_buffer_impl.cc(229)] Failed to initialize command buffer. Segmentation fault (core dumped)
When passing "--platform xcb" to make it use the Xwayland server, it functions normally.
