Correction in milestone typo error-

This is a regression issue broken in M-72 and below is the bisect information:
Good Build : 72.0.3605.0 (Revision : 606282)
Bad Build : 72.0.3606.0 (Revision : 606693)

Chromium bisect URL:
https://chromium.googlesource.com/chromium/src/+log/f090cedb1220fd75864898f936a14f907141b271..86e6511b6b1ee086f50639c9a64346790dea350e

Suspecting : r606619

Leonard@ : Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Note:
1. Issue is not reproducible in today's Stable build #70.0.3538.102
2. Unable to repro issue in Windows (7,8,10) and Linux(14.04 LTS) OS.
3. Unable to provide bisect using per-revision script as it shows "We don't have enough builds error message", hence provided suspect with Chromium bisect.

Thank you..!

marking as RBD, please change accordingly if required.

Reverted, will try to reland later today.

Thanks for the revert, we will verify in next canary.

Please help verify and update this issue, this is blocker for 72 dev release slated for tue nov 13

---------
Update :
---------
Verified above issue in latest Canary build #72.0.3608.0 on Mac(10.13.1, 10.13.6, 10.14.2) OS and the crash issue is fixed. 

Reverted CL (https://chromium.googlesource.com/chromium/src/+/899b84ea267b8ce6ce522d2cf3b34453be3ac164) have fixed the crash issue reported in Comment #0. After detaching a tab, Chrome does not crash and it is working as intended, hence adding TE-Verified labels. Kindly review an attached screen-cast for reference.

Thank you..!
