Errors flash on screen but are not all available permanently for inspection

[absoludity]

Describe the bug
When uploading a credential, I see three separate errors flashing on the screen without being able to read them, before the test finishes and I can only see the detail of one error.

I took screenshots quickly to actually read the errors:

When the test completes, I can only see the detail of the latter:

not the former. The other one is obvious - it was unable to load the schema, but the "Credential Validation" failure is blank and has no details. Possibly it's just a heading for the other two? As in, if the schema or jsonld fails for any reason, then the "Credential Validation" has failed? If that's the case, indenting would indicate that perhaps?

Anyway, I think the errors flashing on the screen temporarily in real-time (and each successive one covering the last) just leaves me thinking "what did I miss", and given the speed of the tests, don't think they are necessary if we provide all the information in the main test output (just my personal opinion).

On another note, when I do look at the details for the jsonld error, it's odd that I need to click twice to get the details. That is, when I click first on details I see:

I'm guessing that this is because if there are lots of errors, it's useful to have them collapsed by default. But maybe a small improvement would be, if there are less than 3 errors, just expand them by default?
