I like the "Rebase" button, but reload of new patchsets flow is very confusing.

I've done the a bunch of times but for example here. https://chromium-review.googlesource.com/c/520607 starting at https://chromium-review.googlesource.com/c/520607#message-1022979d192030816c3fcff8bbbc678358ea0d48 .

I started a CQ, and then 10 minutes later realized it wanted to insist on rebasing on master first (leaving aside whether that's useful behaviour or not...)

So I clicked the shiny Rebase button to rebase it on master. Then when the UI "came back", I clicked "Submit to CQ" and closed the tab.

Half and hour later I checked to see if it had landed, but no, it had uselessly applied the CQ+2 to the non-rebased patchset, so it did nothing.

If I've done those two actions in sequence, the CQ+2 should be applied to the post-rebase patch set. Making the UI flows less racy/confusing would be much appreciated.
