Sticky product summary on Woocommerce single product page

I need to make the product summary on the Woocommerce single product page sticky. I have

.summary.entry-summary{
 position:sticky;
 top:100px
}

And this work, but the summary now sticks even when you have reached the produt tabs and goes on top of these. How can I make the summary stop being sticky when it reaches the product tab section?
