Describe your issue

Similar to #16975 and #16998, there is another issue with SLIM templates. With 4.0.12, the parser fails to handle single quotes (used to enforce trailing white space).

See this example:

div
  'A single quote enforces trailing white space
  = 1234

.text-red-500.text-3xl
  | This text should be red

Here, the class text-red-500 is not processed.

This has been fixed by #17085 and will be available in the next release.
