Stamping after I539 H1B-H4 COS and H4 EAD approval

[aragorn]

I recently filed I539 for H1B- H4 COS and also filed H4 EAD, I got the COS approved and also received my EAD valid till July 2021. Now I am travelling to India, I have my old VISA stamp on my passport for H1 Visa, so I believe I need to go to stamping again to get a fresh H4 stamping.Now if I get a new H4 stamping, what happens to my current H4 EAD, will it still be valid or do I need to apply for a fresh EAD after I come back from stamping?

Thanks
