We have this
When submitting metadata (depicts) via UploadWizard, the statement widget goes into disabled/read mode while being submitted.
After having been submitted, they go back into interactive mode, and one could add new statements, remove statements or make statements prominent (until UploadWizard moves on to the next step)
This can be simulated by uploading multiple files, one of which has little statements (and doesn't take long to submit) while the other has many (and takes awhile): as soon as the first is done submitting, it can be interacted with again until the second one has also completed and UploadWizard moves on...
Any changes that are made at this stage will be pointless, they won't be submitted, and we shouldn't even make it possible to make them.
We want this
It should not be possible to interact with statements once submission has started.
Can be tested on https://commons.wikimedia.beta.wmflabs.org/wiki/Special:UploadWizard
- The statement widgets should be disabled as soon as they're being published
- The statement widgets should remain disabled until UploadWizard moves on to the next step
