Install from Web layout broken

In administrator backend, something broke the grid layout in the "Install from Web" tab. .cb_template .h-100  in bootstrap.css if 100% gives a height like 13000px when window width is >767px.  Only when the package boxes would be stacked does it become legible (normal height).  Of course, disabling flex in .card also makes it normal height.

I see on my production server, CB at 2.9.1 does not have the layout problem.  Perhaps something changed on my development server when I upgraded to 2.9.3.

I'm not sure what you mean. It doesn't have a set height. It'll scroll as far as it needs based off the number of packages shown. Can you provide a screenshot of the issue? Are you using a custom backend template?

Each package box gets 12000+ px height in Chrome or 5000px height in Firefox, so no point in screenshotting all those - just did one.   Notice how the "Directory Permissions" box overlays it at bottom - out of place.

I have not altered Isis. Still running Joomla 3.10.12. I see changes were made to bootstrap.css so I tried the older version  in there, but same problem.

It's not a template issue, but code changes. I copied web developer box from before (working) and after (broken).

Ok, was able to confirm your issue on Joomla 3. Will review providing a fix. Please be sure to include Joomla version with all your posts since you're using a no longer tested version of Joomla (we only test 4 and 5 now).

Please consider at least migrating to Joomla 4. We will be discontinuing Joomla 3 support with the first release of CB 3.x, which will be releasing in the near future. I would estimate you've a few months left before that happens.

Thanks. Will be migrating to J4 soon.

Ok, this will be fixed in next build release of CB (sometime today or tomorrow).
