Description (last modified by kzar)

Background

In order for relative selectors to work properly when combined with our special pseudo classes such as :abp-has we sometimes need to prefix selectors with the ​:scope CSS pseudo class (see #5436).

Unfortunately :scope is not yet supported by Microsoft Edge and therefore filters which use it are ignored.

What to change

  • Detect if :scope isn't available (querySelector() will throw an exception).
  • Switch to alternative method to build the selector if :scope isn't available, likely slower.
  • Ensure to run the test with both code path.

As it is, the alternative has been found by Microsoft now that they are cancelling EdgeHTML.

This bug will fix itself.
