I found that ion-modal is using CoreDelegate to modify the insertion position of DOM elements at display time, which is causing the react event proxy mechanism to break down. Hopefully this will help speed up the fix.

1. ionic-framework/core/src/components/modal/modal.tsx

   Line 450 in 77707b8

   this.usersElement = await attachComponent(delegate, el, this.component, ['ion-page'], this.componentProps, inline);

2. ionic-framework/core/src/utils/framework-delegate.ts

   Line 131 in 77707b8

   app.appendChild(BaseComponent);

I've been struggling with the same issue recently. The workaround I found to enable the usage of IonNav is as follows: (Note: I had actually re-implemented much of my project to use IonNav before I discovered this issue.)

<Modal isOpen={true}>
    <IonNav
        root={() => (
           ... The content of your modal.
         )}
         ></IonNav>
    </Modal>

So, what I'm doing is adding a nested IonNav for the modal, and it works perfectly. This has been the easiest workaround I've found.
