Popup Width allowing non-numerical chars

Done. The MR fixed it: https://git.drupalcode.org/project/ebt_webform_popup/-/merge_requests/5

[OFF] Hey @levmyshkin I was seeing the DrupalBook and is very interesting, when you have the next live booked please let me know and I'll join there

Hi RenatoG, thank you! I will have a look it. We need to support relative width in % and vw. I will think about adding relative units.

Yes, sure, I will finish documentation about EBT modules and schedule next live stream.
