Travel to India with H4 extension pending and with an expired I-94. Can stamping at US consulate save me from H4 abandonment?

My H4 extension was filed with H1b May 2021. H1B for my husband is approved. H4 is still received status. Knowing the current delay in H4 processing I don’t want to wait that long to travel a visit to India. I also know H4 is abandoned if I travel to India. My questions are 1. What does abandon mean? 2. How to reverse abandonment? 3. If I travel to India with an expired I-94 and with H4 pending …what would be the status of my application that is in processing?
