Mat-chip issues for mobile

[Diego Serra]

Hi,

I detected that when using a mat-chip inside a Reactive form in a mobile device, it exists 2 problems:

1. When I press ENTER key, instead add this mat-chip, the result is that I go to the next input field
2. When I press COMMA key, instead add this mat-chip, the result is that I add a "," in mat-chip

Both problems don't exist for desktop

Additional Info: 

Angular core: 7.2.1

Angular material: 7.2.1 

Test example if you open from mobile:

Does anyone have a solution to these problems? 

Thanks

Diego.
