Comment:

 == Test results

 - JetPack slideshow has z-index 1, so using 2 in the theme would solve
 this problem.
 - **Jetpack Image compare has z-index 5, so using 2 in the theme would not
 solve this.**
 - Jetpack Story has z-index 1.
 - **WooCommerce sale and zoom icons which sits over the product image, has
 z-index 9.**
 - Popup Maker -no issues found with or without the PR.


 == What does other menus use?
 - The navigation block uses z-index: 2.
 - Twenty Sixteen z-index: 99999
 - Twenty Nineteen z-index: 99999
 - GeneratePress  z-index: 99999
 - Kadence z-index: 1000


 My recommendation would be to use 9999.

 ----

 The navigation block is also broken in this theme, I will first check if
 there is an issue open for this.
