[4.x]: Duplicate file name issues are not displayed in modal windows

[MoritzLost]

What happened?

Description

I'm seeing an issue where errors on the filename field are not reported when an asset is being edited in a modal window.

When trying to change the filename to a filename that already exists in the same folder, we get an error message below the filename input:

But when editing the same asset in a modal window from an entry form, the validation error is not displayed after trying to save:

I've checked the response in the network request, it correctly includes a newLocation error and an errorSummary with an appropriate message. Only they're not getting displayed, all we get is the generic Couldn’t save asset. message on the bottom left.

Steps to reproduce

1. Open an asset in a modal window from an entry form.
2. Change the filename to a filename that's already used by another asset in the same folder and try to save.

Expected behavior

All validation messages should be displayed in a modal context.

Actual behavior

The validation error message is missing.

Hi, thanks for reporting! I raised a PR for this.

(Also, error reporting in slideouts has been further improved in v5.)

Craft 4.7.3 is out with the fix for this. Thanks again!
