Multiple Clockify buttons appearing in Todoist integration

[codigoisaac]

I am experiencing a recurring UI bug where multiple Clockify timer buttons are injected into Todoist tasks. Sometimes two, or even three, Clockify buttons appear side-by-side to the left of a single task.

Environment:

• Browser: Floorp (Gecko-based)
• Platform: Todoist Web
• Extension: Clockify (Firefox/Gecko version)

Steps to Reproduce & Observations:

1. Standard Load: Open a Todoist project URL or perform a regular refresh.
   • Result: Two or three Clockify buttons appear side-by-side.
2. Hard Refresh (Ctrl + F5): Perform a hard reload.
   • Result: The issue is fixed, and only one button is displayed correctly.
3. Internal Navigation: Navigate to another project and back within the Todoist app (SPA navigation).
   • Result: The duplicates disappear, and only one button remains.

Expected Behavior:
Only one Clockify button should be injected per task, regardless of the loading method (standard load vs. hard refresh).

Note:
The injection script seems to trigger multiple times during the initial page load event, but correctly handles the DOM when a hard refresh or internal navigation occurs.

When loading the page normally:

When hard-refreshing the page with Ctrl + F5, or navigating to another Todoist page an then coming back:
