Angular open modal doesn't get focused

Within my ts file i open a boostrap modal using the .open command.

Then upon pressing the save button another modal gets open and the previous one gets closed.

Here the problem is that the first modal recieves focus on itself and the elements inside it BUT second modal doesn't get focus!

Here is what is happening:

I click a button and i open a modal A
In modal A i have some html elements including two buttons to save and close the modal
If i click the save button from modal A this modal will get closed and another modal will open
This second opened modal doesn't get focus when pressing TAB

Here is a stackblitz: StackBlitz Demo

How this stackblitz works:

If you click the first button is going to open the modal A
then clicking save on that modal will open another modal B
Inside modal B if you try to tab is going to tab on the elements in the background WHY?

I want to give my second modal focus. I tried with Directives and other things that angular suggest but i haven't been able to get it to work.
