Bug Report

Ionic version:

[x] 5.x

Current behavior:

When app is served via ionic serve --project myProject --configuration=sandbox the refresh that takes place after changes are saved, is significantly longer than using ionic serve --project myProject (Note: no --configuration flag).

Expected behavior:

The refresh should take the same amount of time as ionic serve --project myProject.

My workaround is to take the contents of environment.sandbox.ts and copy them into environment.ts. Then I run ionic serve --project myProject. This resolves the slow performance I am seeing.

Steps to reproduce:

1. Create a new environment file. (i.e. environment.sandbox.ts)
2. Copy contents of environment.ts into your new environment file.
3. Add the appropriate entries in angular.json.
4. In Ionic CLI, run ionic serve --project myProject --configuration=yourConfig
