Exception values with many newlines make issue details page difficult to read

### Environment

SaaS (https://sentry.io/)

### Steps to Reproduce

Open an error in issue details which contains lots of newlines, it eats up an enormous amount of vertical space on the page.

### Expected Result

Probably some sort of auto-collapsing - long messages should not ruin the page experience.

### Actual Result

Start by reproducing the issue in the linked Sentry issue details page with an exception containing many newlines, using the attached example as a reference. Investigate how the long exception value is displayed and define a collapsed presentation that preserves access to the full value without consuming excessive vertical space. Done means the details page remains readable while the complete exception can still be viewed.
