I see what you're saying now from the CL - if the shell version doesn't update then we won't ever update webapks? That's pretty bad. Requesting merge of above (1-line change) to branches.

Your change meets the bar and is auto-approved for M59. Please go ahead and merge the CL to branch 3071 manually. Please contact milestone owner if you have questions.

Had this been requested sooner, we could have taken it, but as is it is too late.

Ok, but if we respin the build, can we reconsider this? THe codepath is only reached if the user opens a WebAPK so risk is low.
