How can I have tee to wait for all processes?

Given the following example:

$ echo foo | tee >(grep -o oo); echo bar
foo
bar
oo

As you can see, echo bar is called before grep -o oo has terminated.

(How) is it possible to achieve the following output instead?

foo
oo
bar

Thanks in advance!

The problem is that the process substitution runs that command in the background.

Put the second echo inside the process substitution.

echo foo | tee >(grep -o oo; echo bar)
