Newlines in string XCom values were shown as spaces in the XCom tab.
`renderTextWithLinks` in `XComEntry.tsx` split the text on `\s+` and joined
the parts back with a single space, so newlines were removed before
rendering.
Changes:
- Split with a capture group (`/(\s+)/`) so whitespace is kept.
- Add `whiteSpace="pre-wrap"` so the browser shows the newlines.
- Add `maxHeight` with scrolling for very long values, as suggested in the
issue.
- Add `overflowWrap="anywhere"` so long strings without spaces don't stretch
the table.
- Add tests for newlines and for links inside multi-line values.
This PR only covers the XCom tab. The HITLOperator body part of the issue is
not
included.
