[Johannes29]

• [x] I am on the latest ActivityWatch version.
• [x] I have searched the issues of this repo and believe that this is not a duplicate.

• OS name and version: Windows 11 version 22621.1105
• ActivityWatch version: v0.12.1

Describe the bug

When the mouse leaves a "day" rect in this svg,

this error is thrown in the devtools console:

periodusage.js:111 Uncaught TypeError: Cannot read properties of undefined (reading 'undefined')
    at SVGRectElement.<anonymous> (periodusage.js:111:19)
    at SVGRectElement.<anonymous> (on.js:3:14)

To Reproduce

1. Open the dashboard via the tray icon
2. Click on Activity in the top left corner
3. Move the mouse over a "day" rect
4. Move the mouse outside of the "day" rect
5. Open devtools console
6. See error

Expected behavior

When the mouse leaves a "day" rect, no error should be thrown and the color should return to normal.
