Event 5031 logs previous theme version after WordPress automatic theme update

WP Activity Log appeared to record the previous Divi version (5.12.1) as the “new version” after WordPress successfully auto-updated the theme to 5.13. I’ve attached screenshots showing the incorrect activity-log entry and the actual installed theme version.

Steps to Reproduce

1. Install and activate a theme with an available update. In my case, I was on Divi 5.12.1, and then Divi 5.13 became available.
2. Enable WordPress automatic updates for the theme.
3. Allow WordPress to perform its normal scheduled automatic update.
4. After the update completes, check WP Activity Log Event 5031 — “User updated a theme.”
5. Compare the version reported by Event 5031 with the version actually installed.

Expected Result: New version in the text shows the new version, 5.13 in my case

Actual Result: New version shows the OLD version, 5.12.1 in my case

I also verified the installed version independently with WP-CLI:

wp theme get Divi --field=version

which returns:

5.13

The Event 5031 “More details” data contains:

Theme:
Name: Divi
Version: 5.12.1

ThemeStatus: Active
Object: theme
EventType: updated
UserAgent: WordPress/6.9.7; [site URL]
Username: Unknown User

• WordPress: 6.9.7
• WP Activity Log: 5.6.6
• Theme: Updated to Divi 5.13
• Theme auto-updates: Enabled in WordPress

Additional context / possible cause — AI generated

I investigated this with AI assistance, and it may be related to theme metadata caching during automatic updates.

Event 5031 reads the updated theme version using wp_get_theme() during upgrader_process_complete. WordPress automatic theme updates use clear_update_cache => false, so it seems possible that WP Activity Log may be reading the cached pre-update theme version before WordPress refreshes the theme cache.

That could explain why Event 5031 recorded 5.12.1, while the installed theme and subsequent checks report 5.13.

Are you able to take a look and advise?
