Signup: Invalid parameter value if username contains spaces

If user tries to create one account with username with spaces it's breaks all

 

Maybe fix can be 

 
username: this.signupForm.value.username.trim().toLowerCase(),

to -->
username: this.signupForm.value.username.trim().toLowerCase().split(' ').join(''),

In the file --> src/core/features/login/pages/email-signup/email-signup.ts

EDIT: This issue seems to affect the "Lost password" form too.
