mat-card-actions has inconsistent spacing

[kyletanders]

Bug, feature request, or proposal:

Button spacing in mat-card-actions is different between the 1st and 2nd button and the 2nd and 3rd button.

What is the expected behavior?

Spacing should be consistent.

What is the current behavior?

Spacing is not consistent

What are the steps to reproduce?

https://stackblitz.com/edit/angular-fjkrkb

Look at spacing between the buttons in mat-card-actions and see that they are not the same

What is the use-case or motivation for changing an existing behavior?

Seems like a bug

Guys what is justification for having negative margin on mat-card-actions ?

[crisbeto]

I think the reason for the negative margin is to prevent the actions' margin from overlapping with the card's padding.

will this be fixed at any time?

Since the latest release selectors should be change to .mat-button-base, I had a issue as .mat-flat-button and .mat-stroked-button are absolutely ignored in .mat-card-actions and .mat-dialog-actions. The part with the dialog has been fixed, but with the card hasn't, but I can't reopen it.
