When you are trying to configure a pipeline from SCM, and select the SCM, below Credentials appears a big blue cross, when using Firefox, version 102.12.0esr. Issue does not appear in Chrome.

Reproduction steps:

• In the controller that is running with the support bundle using Firefox, version 102.12.0esr, go to New Item → Pipeline (name the pipeline).
• Go to Advanced Project Options, in Definition combo, and change to Pipeline script from SCM.
• In SCM combo, select Git, and then you can see a big blue cross displayed (see screenshot)
• If you select the 'Add' option displayed next to the blue cross, you are able to add a new Credential - so the button is not borken, just rendering incorrectly

The culprit:

• https://github.com/jenkinsci/credentials-plugin/blob/402df1d1f4f5f6c86d1768762773e4868ad1629d/src/main/resources/lib/credentials/select.jelly#L118
• https://github.com/jenkinsci/credentials-plugin/blob/402df1d1f4f5f6c86d1768762773e4868ad1629d/src/main/resources/lib/credentials/select.jelly#L151

If you look at the inspector, when the add buttons are added, they are added with a svg, when testing this if you delete the svg part, the page renders correctly.

Other notes:

• Could be linked to my earlier PR here - https://github.com/jenkinsci/credentials-plugin/pull/422 - I manually tested at the time with different browsers and saw no issues.
• Possibly linked to JENKINS-23405
