Comment (by jipmoors):

 Looking at the original problem and the current code.
 I have a hard time deteremining the problem, if there is any.

 The original problem was that a variable was used to construct a regular
 expression query, but that has been rewritten in the meanwhile.

 Currenty the id_base is used to construct a string which is most likely
 (always?) used to fill an HTML ID or FOR attribute. These used to be
 restricted on how they had to be restricted but since HTML5 this is very
 loosly defined: https://html.spec.whatwg.org/multipage/dom.html#the-id-
 attribute

 Since everything is working and no other reports have come in, I suggest
 closing this issue.
