Wrote up some ideas for removing jank from the bridges. https://docs.google.com/document/d/1b2igeRoGXpdr_B89W7n2CaiXTspXq9tnrK5ocsyhNNM/edit#
Includes content from CB-3900, which I'd previously brought up on the ML. Also relates to CB-3359 for one of the ideas. Feel free to give it a read, add comments & share thoughts of what other improvements we could make. Andrew
