Activity feed missing commits for other users

[amix307]

Description

Some users can see the full commit/event history in other users' activity feeds, while others see only the heatmap — the detailed list of commits is missing. This does not affect administrators, who always see the full activity.

Problem Description:

The issue is inconsistent and not tied to specific repository settings or user permissions. For some users:

• When viewing another user's activity tab (e.g. https://gitea.example.com/username1?tab=activity), the heatmap is visible and shows activity.
• However, the commit list below is either missing entirely or incomplete — even when both users have write access to the same repositories.
• For some users, the full activity feed is visible as expected.
• Admin users always see the full commit list regardless of user or repo.

In a specific case:

• User username2 views the activity tab of username1.
• The heatmap shows activity, but the commit list is empty for the last 7 months.
• Direct links to specific commits by username1 do work for username2, and access to those repositories is confirmed.
• This indicates that the underlying permissions and visibility are correct — the problem seems to affect only the activity feed rendering.

What I Checked:

• Repository visibility: public or limited
• User permissions: same (writer)
• Organization membership: same
• Activity visibility settings (e.g. Keep activity private): tested both enabled and disabled — no effect
• Browsers, cookies, sessions — no difference
• Reproduced across multiple accounts and devices

Expected Behavior:
Any authenticated user with access to the repositories should see both the heatmap and the full list of commits/events in another user's activity tab.

Actual Behavior:
Some users only see the heatmap; the commit list is missing or incomplete. This behavior is inconsistent and affects only certain user pairs.
