Memory leak?

I suspect this applet is slowly leaking RAM.

After four days of uptime:

    PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
   1262 birdie    20      655.6m  75.6m  43.9m S         0.5   1:16.19 panel-30-weathe
   1259 birdie    20      630.5m  68.6m  40.6m S   0.7   0.4   1:05.64 panel-24-weathe

Let's restart (xfce4-panel -r):

2274814 birdie    20      544.5m  55.1m  31.0m S         0.3   0:00.63 panel-30-weathe
2274811 birdie    20      398.7m  53.6m  31.1m S         0.3   0:00.57 panel-24-weathe

Maybe it's because I've changed options for both applets, I'll keep watching.

I'm using fully updated Fedora 37, xfce4-weather-plugin-0.11.0-4.fc37.x86_64.
