IMHO the behavior got actually worse:
- Copy 978-3-642-14564-3
- Open a page for editing in VE, type "ISBN ".
- Paste the copied ISBN.
- Try to get it autolinked.
Result in 1.29.0-wmf.15: It will get linked if (and only if) you type a space. Result in 1.29.0-alpha: No matter what you do, the ISBN will not be linked. Desired result: It should get linked either directly after you paste it or at least after your next action (whether you type anything or move the cursor or whatever)
If you delete and re-add the last character it works (because it's typed content), but…
