It's not in QGIS. It's in Qt, but can't be used from QGIS. QtWebengine
requires some initialization steps before construction of the
QApplication used by QGIS, and unfortunately these steps introduce an
incompatibility in OpenGL handling which breaks the QGIS 3D
functionality.

Pending an upstream Qt / Webengine fix we can't resolve this
situation, and Qt Webengine is not a possibility for use in QGIS.

The Webkit engine used seems to be very outdated and not possible to render modern web pages. For example, the engine used in QGIS 3.30 dated back to 2016: AppleWebKit/602.1 (KHTML, like Gecko) QGIS3 Version/10.0 Safari/602.1.
