JS error in the backend when inserting a Forms Delete Post Link to a Toolset “Fields and Text Block” using non-Latin characters

Symptoms

The Toolset Blocks plugin offers a TB Fields and Text block. Among other things, this block allows you to insert a Toolset Forms Delete Post Link.

If you happen to insert a non-Latin character to the Link Text when inserting the Toolset Forms Delete Post Links, an error is thrown in the console while editing a post.

Additionally, the “Preview” of the link will not load and the block preview will keep saying it’s “Loading”.

Workaround

There is no other workaround currently but using custom HTML links. You could also ignore the error for now, since the problem does not appear on the front-end and the link will work fine.
