Hi. I was the one who originally submitter the issue to your support. In case you have any questions :)

@HealperDK thanks for the awesome example repo!

It's clear from that example that the dialog.showModal() method is putting it's content on the very top of everything, and our feedback form can't compete, even by adjusting the z-index to outrageous levels.

I think this stack-overflow question and answers summarize the situation:

• https://stackoverflow.com/questions/75509725/place-an-element-above-the-top-layer
  And also this MDN article which calls out .requestFullscreen() and .showPopover() as well as .showModal():
• https://developer.mozilla.org/en-US/docs/Glossary/Top_layer

What we can do is see if the feedback form can use .showModal() internally so that it can be on top of the dialog in the example repo. What I'd want to check though is;

• does it actually solve the problem when there are two modals on the page, or does one replace the other?
• does the 'take screenshot' interaction still work ok, with or without other modals on the page?
• does it significantly break css or other customizations folks might have applied to the form? will we need a major version bump to land it?

What I would suggest to you in the mean time is to explore mounting the feedback into it's own <dialog> and call .showModal() on that in order to raise it to the toplayer of the page.
Something like this looks like a start, but has some problems still:

Thanks for the suggestion of mounting the feedback form onto my own dialog. I hadn't thought of that.

I managed to get it working.
If anyone else needs this I will post my solution here. It needed a bit of event handler shenanigans before it worked properly for me.

const form = await sentryFeedback.createForm();
form.appendToDom();

// Create a hidden dialog to hold the feedback form
const invisibleDialog = document.createElement("dialog")
invisibleDialog.classList.add("transparent-backdrop");  // Hide the backdrop
invisibleDialog.style.border = "none";  // Hide the rest of the modal
document.body.appendChild(invisibleDialog);

// Find the node containing the feedback form and add it to the hidden dialog
const feedbackNode = document.getElementById('sentry-feedback')
invisibleDialog.append(feedbackNode);
invisibleDialog.showModal();

// Now we can open our form
form.open();

//For the form to work correctly we need to add certain event listeners
invisibleDialog.addEventListener("close", (event) => {
    // Remove entire dialog from the DOM when it is closed
    invisibleDialog.remove()
});

invisibleDialog.addEventListener("click", (event) => {
    // When dialog (backdrop) is clicked, close the dialog
    invisibleDialog.close();
});


form.el.querySelector('dialog').addEventListener('close', () => {
    // When form is close also clsoe the dialog
    invisibleDialog.close();
});

// Find the cancel button. Its the last of the default buttons. Not ideal but there is no good selector to 
// use here
const defaultButtons = form.el.querySelectorAll('.btn--default');
defaultButtons[defaultButtons.length - 1].addEventListener("click", () => {
    invisibleDialog.close();
});
