Rendering issue with UI using the Add Addon button.

Description of the issue

I am attempting to migrate my docker HA setup to running entirely within a VM. I have HA in a VM, and now the next step is to move MQTT and Zigbee2MQTT from docker to variants running inside the HA VM via addons. Installing MQTT was easy enough as it is part of core, but I'm having an issue installing Zigbee2MQTT via the instructions on this repo. I have recently upgraded to 2025.1.2, and I'm wondering if that might be part of the issue.

Here are the symptoms I'm seeing. On my main machine I navigate to this github README page and click the "ADD ADD-ON REPOSITORY TO MY HA) button. This pops up a page asking me to open the page in my home assistant. I set the URL to the VM's IP address and click "Open Link".

This is where I start encountering issues. It pops up my HA web interface with a dialog box, but it only contains a text box with the github URL in it and nothing else. I'm wondering if this is a rendering bug, and I just pressed enter in case there was some invisible button to accept something (probably not the best idea to blindly do that, but that's what I did). Next a similar dialog popped up with similar issues, and I stopped to write up this report.

The dialog I'm at now looks like this:

If I close the page and retry clicking the "ADD ADD-ON" button, it brings me back to that dialog.

It looks like the issue is a bad rendering because if I ctrl+shift+c in chrome to bring up the dev console I can see there are some invisible elements:

I'm not a web dev, so a bit out of my element here, I wanted to past the html for the elements, but for some reason it don't grab the entire thing? So here is a screenshot. It looks like the buttons just have no text.

FWIW, I guessed and clicked the invisible button and it looks like I was able to install fine, so it seems like some rendering bug.
