Coverage not working with mypy ignores and vague errors

Bug Report

(A clear and concise description of what the bug is.)
Coverage not showing the same result as mypy

To Reproduce

class A(BaseModel):
   b: str = Field(default=..., description="some var")

Expected Behavior
To get the code coverage based on what I get with the mypy src call

Actual Behavior

I'm getting low coverage despite mypy not complaining after these ignores
Ignore missing imports and no warn unused ignores just doesnt apply to coverage, it shows passed when using mypy src but fails on coverage

Your Environment

• Mypy version used: latest
• Mypy command-line flags: mypy
  --disallow-untyped-calls
  --disallow-untyped-defs
  --check-untyped-defs
  --follow-imports=normal
  --explicit-package-bases
  --allow-untyped-globals
  --ignore-missing-imports
  --no-warn-unused-ignores
  --warn-return-any
  .
• Mypy configuration options from mypy.ini (and other config files):
• Python version used: 3.13.2

Start by reproducing the report with the provided Python snippet and the listed mypy command-line flags, then compare the normal mypy result with the coverage result. The issue does not name an implementation file or test, so locate the coverage entry point and existing coverage tests before proceeding. Done means the handling of ignored imports and unused ignores is consistent between mypy and coverage.
