Description of problem:
On some pages of Content view version comparison the version number disappears

Version-Release number of selected component (if applicable):
Satellite 6.13 SNAP9

How reproducible:
always (with lower screen resolution or small sized browser window)

Steps to Reproduce:
1. Sync a repository that contains some erratas (e.g. RHEL8 BaseOS)
2. Create a Content view, add repositories from previous step, publish at least two Content view versions
3. Compare the two Content view versions and go to "Errata"

Actual results:
Some erratas have too long Title and Type so headers of other columns get shortened. Headers of last two columns that should show the compared versions are shortened to "Version...", so the version numbers are not visible.

Expected results:
The version numbers should be always visible. The header may be split into two lines or the prefix "Version" could be removed.

Additional info:
Observed on Errata comparison, but may be on other tabs with many and/or long columns listed.
