did you think about solving this issue in javascript only?

Yes, group most of them into a vue/angular directory. but the getHelp() doesn't like span matomo-help-link base="https://matomo.org/docs/" text="test"></span> or VUE version <helpLink base="url" text='test'/>, not too sure why, but update the regex, should be better

This issue is in "needs review" but there has been no activity for 7 days. ping @matomo-org/core-reviewers
