I don’t think the kernel is at fault.  This is usually a problem with
gstreamer only.  Do not forget about environment variables.

I’d suggest looking for gstreamer debugging options and tracing the
discovery of plugins specifically.

I’m seeing the same behaviour in epiphany (and eolie), both webkit
browsers.  I have these gstreamer packages installed:

gst-plugins-good	1.14.3	out	/gnu/store/ar5i930rzx6gx0fllxlj7v0di8av98dn-gst-plugins-good-1.14.3
gst-plugins-ugly	1.14.3	out	/gnu/store/7w2bqvdnylh4y87m6r40k644pxd17g3x-gst-plugins-ugly-1.14.3
gst-plugins-bad	1.14.3	out	/gnu/store/x8m0kdj9x6smm6ybwd3rzkcpqw809pim-gst-plugins-bad-1.14.3
gst-plugins-base	1.14.3	out	/gnu/store/hyjjxxc2q5sfhkmm9iq3g34afm21b62v-gst-plugins-base-1.14.3

I used to also have gst-libav, which made a lot of things work better at
a time.

Relevant environment variables:

    GST_PLUGIN_SYSTEM_PATH=/home/rekado/.guix-profile/lib/gstreamer-1.0:/run/current-system/profile/lib/gstreamer-1.0
    GST_PLUGIN_PATH=/home/rekado/.guix-profile/lib/gstreamer-1.0
