Report all issues with a complete plugin list (reporting this as an issue in the changelog isn't helping anyone)
Check if your plugin already has an issue reported https://issues.jenkins.io/issues/?filter=22840 (artifactory plugin is https://github.com/jfrog/jenkins-artifactory-plugin/issues/350
If you know which plugin is causing the issue report a new issue, including steps to reproduce and screenshots and label it with 'tables-to-divs-regression'
Historically, jenkins's jelly framework generated lots of tables. These tables are very mobile hostile. The ui it generates is also not in line with modern UIs.
Here's one example from Windows 10's settings:
Note that the label for a field is above the field – not to the left of the field.
Here's a much older UI from Windows:
Note that the labels for checkboxes/radios are to the right of the buttons, not to their left (* with RTL layouts, this changes, but that's due to mirroring and applies to almost everything).
Even so, labels for other things are above, not to their left (see this example for invitation duration – which is also pre Windows 10):
Examples can be seen in macOS, Maemo / MeeGo, and pretty much every system (including Chrome / Firefox / Android).
This issue tracked the core jelly changes made to switch from generating tables to generating divs.
