Steam tray icon expands horizontal size.

[xnrdotone]

Describe the bug
When I open steam the tray icon expands horizontally and the new icons appear in a new column despite the fact I set the grow to south.

To Reproduce
Steps to reproduce the buggy behavior (even if intermittent):

1. Use WM Openbox.
2. Use my config.
3. Launch the app Steam.
4. See that the Steam icon takes double the space.

Expected behavior

Log files
I technically can not get a log file of the error because when I restart stalonetray manually everything works as expected. But for the good measure here is the log after restarting:

trace.txt

And here is my config:

Maybe try kludges force_icons_size?
From the option description, it seems relevant.

It solves the problem of the icon expanding the tray horizontal size but doesn’t resize the icon accordingly, so the tray would be the right size and it would just show an icon of the current size, but clipped out.
