Link/Unlink partial unlinking not working anymore

[hjanuschka]

🙌 dear maintainers! thank you for keeping this project up!

we recently made a upgrade from a super old tiny deployment to a newer one, which went 99% flawless :)
however, one, "bug" or "behavioural" change popped up.

between 5.0.0 and 5.0.1 there seems to be a change made that changes the unlink button.

<= 5.0.0 --> if you had a link with multiple word's - unlink unlinked only the selected characters

• https://fiddle.tiny.cloud/4RTwVxU8kL/2

>=5.0.1 ---> no matter what is selected the link is removed completely

• https://fiddle.tiny.cloud/4RTwVxU8kL/3

bisecting the commits, 5.0.0...5.0.1
i guess it is related to this commit: 64ea6d5

as a workaround - calling execCommand("unlink") does the trick.

tinymce.get("content").execCommand("unlink")
