Block Data Attribute Plugin - Can't type / or \ in the Value field.

This site is best viewed in a modern browser with JavaScript enabled.

I have to add a data attribute to one my of blocks and I've found this plugin developed by you.

Unfortunately, the plugin doesn't allow me to type slash (/) or backslash () in the Value field.

I know this is blocked with Javascript but I wasn't able to figure out which line of the code is causing this.

Can anyone assist me, please? I really need this.

Thank you!

Thanks for pointing this out, I will update the plugin to address this issue.
