TL;DR version:

 

We're testing a retroactive fix that we hope to include in the upcoming patch.

 

For now, if you've completed/acquired Bronze Beneath the Lake and Winds of Steel, a workaround entails angering one faction or the other (no need to anger the three of them). In those cases, Webb will let you into the hearings after you tell her that the bridges are burnt with all factions.
