cubicweb #3400448 workflow and schema images disappear on first use [resolved]

As of today, they are wiped on the first render of the src attribute, cubicweb-side. Calling the src uri a second time (e.g. because one wants to "copy image location" to see it better) yields a logged crash. They should be e.g. in some appdatahome/uicache subdir and remain there. Or we build inline svg and the tmppng hack can go away.
