When using a non-tracked org, the 'Push-or-deploy-or-save' setting will try to save JEST test files to the org, but it shouldn't. Since the force:source:deploy command doesn't use the .forceignore file, it isn't ignoring the 'tests' directory.

Describe the solution you'd like
A clear and concise description of what you want to happen.
Have the 'force:source:deploy' use the .forceignore file so the files/directories listed in there are not pushed to non-tracked org when you try to save a JEST test file and you have the 'Push-or-deploy-or-save' setting enabled.
Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
Turning off the 'Push-or-deploy-or-save' setting and manually deploy the files I need to non-tracked org
