> I am experiencing an error in a CI job in GitHub in some packages I currently maintain (verilog-ext and

> In both of these packages (verilog-ext and vhdl-ext) I have created an `xref` backend based on tree-sitter.

Judging by the log, the failures are due to differences in text
properties, and specifically to the differences in the 'fontified'
properties. Why is that significant for your test? The 'fontified'
property is used internally by JIT font-lock feature of Emacs, so it
shouldn't matter to any Lisp program, unless the program is somehow
related to font-lock machinery.
For that matter, how about telling more about what
test-hdl-files-equal does and what is its purpose and main ideas of
implementation? It's hard to tell anything intelligent without some
additional information.
