ArgoCD doesn't show diff for suspended CronJob

Checklist:

• [x] I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• [x] I've included steps to reproduce the bug.
• [x] I've pasted the output of argocd version.

Describe the bug

During a migration, we disabled sync and suspended a number of CronJobs. After enabling sync (and running a manual sync), the CronJobs are still suspended and there is apparently no diff even though I can see it

To Reproduce

1. Create CronJob (without the spec.suspend key
2. Disable Auto-Sync in ArgoCD for the application
3. Suspend the CronJob spec.suspend: true
4. Enable Auto-Sync in ArgoCD (or manually Sync)
5. Observe that the CronJob still shows successful sync, but spec.suspend: true still appears in the Live Manifest view.

Expected behavior

I expect the manifest to sync with the git repository (for spec.suspend: false or nothing to appear).

Version

I'm using an older version of ArgoCD due to oAuth issues - perhaps those are resolved and I can upgrade now.

The issue is present on v2.3.3+07ac038 as well. I am not using AutoSync, but editing the CronJob's suspend field never shows any diff (and Sync has no effect). (Hard) Refreshing does not change anything.

[andrii-shevchyk]

The same story with volumes/volumeMounts, you can change those fields manually and ArgoCD won't notice that.

Interesting, from my side ArgoCD does not show diff for serviceAccount

[fredleger]

Same in argocd 2.6.0

[PrayagS]

+1 for ArgoCD (v2.4.14) not recognizing suspend: true and nodeSelector/tolerations changes in the diff.

Created a new CronJob with suspend: true, and it got synced with suspend: false, which is a bit alarming.

v2.11.2+25f7504

[henryzhao95]

Seeing the same as @gnarroway-bullish with v2.9.5+f943664 where:

• suspend: false in git does not appear in the desired Argo CD manifest
• suspend: true in git syncs as suspend: false in K8s

[nerzhul]

we noticed also the same issue, if we edit a cronjob to set suspend: true from argocd UI there is no diff shown in UI then we cannot remind at a point that the cronjob was suspended
