    Might this fix be the cause of our webgl crashes introduced since 2021.3.10?
    Our WebGL application now crashes at a point where textures are loaded via webrequests, and sometimes interupted before they get to finish.
    The crashes started since 2021.3.10, and do no occur in 2021.3.9. This bugfix seems to be the only thing that is the plausible cause, because this is the only change related to unitywebrequests and textures
