Display full error message in tooltip when hovering over error message in issue feed if message has been truncated due to length

### Problem Statement

The issues results list in issue feed often has to truncate displaying the full error message or an issue because it is too long (which I think is fine). But it is sometimes annoying to have to click into the individual issue to see the full error message as a lot of time the most important/specific part of the message is towards the end.

### Solution Brainstorm

It would be great if the full error message could be displayed in a tooltip if you hover over the error message similar to the way that the stacktrace is displayed in a tooltip if you hover over the error type in issue feed.

### Product Area

Unknown

Start in the issue feed UI where long error messages are truncated, and compare it with the existing stacktrace tooltip shown when hovering over the error type. Confirm the desired behavior by reproducing a long message in the issue results list; done means hovering the truncated message reveals its full text without opening the issue.
