[FIX] web: regex syntax unsupported by Webkit

Positive Lookbehind regex syntax is currently not supported yet by
Webkit, and thus Safari (both on macOS and iOS) resulting into a crash
as the syntax is not recognized.

This issue affects both frontend and backend.

This commit fixes it by reimplementing the feature without using this
syntax.
