Mocha is not running all UT when any test is in sub folder

[kmorcinek]

Right now all UT are in folder /tests. When any new UT is created in sub folder, only that new test is running after npm test.

In package.json there is the default command for running tests:

"scripts": {
  "test": "mocha -r ts-node/register tests/**/*.test.ts",

Reproduction can be found on branch https://github.com/kmorcinek/conqueror-browser-spy/runs/1270882356?check_suite_focus=true where only 2 UT from SeasonsTest were executed.
