Sync master -> staging

[0xdevalias]

(note: this is a re-creation of #1085 so I can fix the conflicts on a branch that isn't master)

Syncs the following changes in master (including 'direct to master hotfixes' such as #1059) back to staging to keep the branches aligned:

@mike-lvov if we do hotfix changes directly to master in future (which I would like to avoid the situations where we need to in the first place), please make sure you sync them back to staging straight away afterwards to avoid situations like the conflicts here.

[CRO] the differences here seem like we aren't losing any relevant changes from staging now, though they are so minimal that i'm not actually sure what we gained by making #1059 directly against master. Perhaps it's that we have since re-fixed a lot of that stuff manually in staging anyway?
