Describe the bug

Description

• forge coverage report shows seemingly-accurate percentages of tested functions for some contract files, but 0% for one that clearly has functions tested: src/ParachainRegistry.sol. The relevant test file is test/testParachainRegistry.t.sol.
• To reproduce, run forge coverage for this repo here.
• Example output that shows the behavior:

>>> forge coverage

Apologies if this is a duplicate issue, but I didn't see the specific case searching, or here, but maybe related to this one.
