Comments of 2 changesets replaced

[anonymous]

What steps will reproduce the problem?

1. (Maybe) Upload 2 or more changesets within a few minutes

What is the expected result?

Every changeset should have their own changeset comment

What happens instead?

The 2 changeset comments replaced!! (changesets 27987526 and 27987504)

Please provide any additional information below. Attach a screenshot if possible.

A few weeks ago this happened too, but then I thought it was my fault. Now I'm pretty sure, that I gave the correct comment to each changeset!
