Bug 1690793

python-sphinxcontrib-websupport 1.1.0 fails the tests with import errors on sphinx.websupport.

upstream master fixes the issue (changes sphinxcontrib.websupport), but the entire test suite fails.

this is a problem for the 3.8 bootstrap. yet not a big one, as sphinx no onger requires sphinxcontrib-websupport.

Here (before Sphinx 2.0.0, with 1:1.8.4-1.fc30): https://src.fedoraproject.org/rpms/python-sphinxcontrib-websupport/pull-request/3 the failure was:
