"Force push" noise in PR history toward top of stack

[clintandrewhall]

I'm loving stacks so far, especially the one-click stack rebase in the UX!

The only complaint I have thus far is the "force push" noise that happens toward the top of the stack as changes are made toward the bottom. Case in point: elastic/kibana#271121

You can see how the refs quite literally following each other: 3801441 to eeee1e6 to 543543e, etc:

Perhaps you could consider "bundling" sibling force-pushes into an accordion, or combining them all into one sentence? I'm not sure the value in having a record of refs, but grouping them together might make sense.
