Given the issue appears between 9.0.19 and 9.0.20 a Tomcat issue looks more likely than a browser issue. If I point you towards a test build (no guarantees, use at your own risk, if your server catches fire don't blame me etc.) for 9.0.21 could you test that as there are some HTTP/2 changes in 9.0.20 that made a long standing bug more likely that have been fixed in 9.0.21-dev. If you still see the issue then we can look at specific debug logging and/or isolated test cases.
