Attribut Value Validate Regex not executed

Version: pim: 1.5.48, core: 1.4.78
When adding an regular expression to a Attribut with type string, the given value in the product detail page is not getting validated.
Example:
Attribut, string
Regex: /\d\d[.]\d/
Value inserted: string
saved, no issue

Regex in general works, as when you remove the regex from the attribute and set it again, then the system recognizes that there are inproper values in the attribute values. So regex validation just happens while the attribute is saved, not when value is saved.
I guess this behaviour is not intended.

You may should change your RegEx as follows: /^\d\d[.]\d$/

It's not about the regex, it's about when it fires

When creating a attribut with a regexstring, let's say super simple [A-Z] than it's possible to save the attribute. Now edit the attribute, delete the regex, save. Now try to add a regex string: Fehler 400: Dieses REGEX-Muster ist nicht gültig.
Doesn't matter what I enter, it's not possible to save. In the Help Center I can also not find anything about regex. A field that is not supported anymore?
