Thanks Julie for reminding me of this thread!
I agree we can only build ui-deps package when the review is about to merge.
I've proposed https://github.com/rdo-common/openstack-tripleo-ui-deps/pull/19
which allows us to build the package with the review and patchset
numbers, before it's merged.
Please review and we can try it on the next deps update!
