jest --watch doesn't show coverage

[laggingreflex]

Running jest --watch with collectCoverage: true and collectCoverageFrom: ['src/**/*.{js,vue}'] doesn't show coverage.

It works as expected when running just jest, but problem arises when running jest --watch

To Reproduce

Run jest & jest --watch in the reproduction repo

Expected behavior

jest works as expected, shows coverage info

> jest

 PASS  src/test.js
  test
    √ test (3ms)

Thank you for the bug report, but it doesn't look like this is caused by vue-jest (since there are reports in the linked issue for users not using vue-jest)
