Comment (by Krstarica):

 I'm not happy with using shortcode as an attribute, but other approaches
 are just way too slow, like parsing HTML.

 It seems that the real issue here is that function wp_kses_attr_parse()
 which finds all attributes of an HTML element does not work properly. It
 assumes hyphen cannot be a part of HTML element.

 All AMP tags (e.g. amp-img, amp-video, amp-audio, amp-iframe, amp-form)
 contain hyphen and all other custom HTML elements:
 https://amp.dev/documentation/guides-and-tutorials/learn/spec/amphtml/
 https://html.spec.whatwg.org/multipage/custom-elements.html

 The consequence is that shortcodes inside such tags do not work.
