Given that this has the potential to mislead developers with Feedback reports with incorrect logs (logs from the correct time for example, are super important to things like, for example, touchpad issues), I would say we need this for the current milestone.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/9c678f28bc8b50041b8aaa700714c75cd02b19f4

Fix sending multiple feedback reports within short durations of each other

Those reports needed to be queued nicely and each report should be sent
with its correct respective system information not the one of the previous
report.
