noVNC connection timeout with Internet Explorer 9

+++ This bug was initially created as a clone of Bug #33968 +++ A customer reported a problem with IE9 connecting to a VM using noVNC: 1. The first attempt times out. 2. Reloading the page with F5 does not work 3. Closing the tab and opening a new one from within the UVMM UMC module works. Doing the same with Firefox works on the first try.
It seems that the connection timeout is too short: https://github.com/kanaka/noVNC/issues/238 -> Bug #34193
IE < 11 is out of support: Bug #40402.
