Looks like a regression was introduced. Suddenly clicking links in the structured data interface opens in new windows. This is intrusive, annoying and completely out of touch with the rest of the interface. Also the class "extiw" attached to it seems a bit weird. Please remove this feature (or bug).
This has been default behavior for months (see T216450). We're open to discussions about changing it if there's a large community desire to do so, but this is the first time I'm aware of anyone mentioning it, and there were multiple reasons for implementing it in the first place, including but not limited to:
- not taking users away from the context of the Commons page they're mainly interested in
- allowing users to see Wikidata items without having to discard in-progress edits on the Commons page
- and more
It's obviously not technically a hard thing to change, but we did go through numerous discussions about it before we released depicts in April. If it turns out the behavior is hindering editing flows for many users, we'll look at alternative solutions, but we'd need more feedback to justify that.
My usual behavior is (and surely will be) to open these kinds of links in new tabs even if they don't have a target="_blank". Which doesn't necessarily mean my behavior is perfect, of course. :-)
