Battery full-at sometimes displays zero

[samhh]

Using the new full-at option for the battery module in 0.9.2, it sometimes displays the correct number, and sometimes displays zero. I haven't nailed down why this is yet, I'll pop back with a more helpful repro if I figure it out. In the meantime, here's the relevant part of my config:

"battery": {
    "full-at": 72,
    "states": {
        "warning": 30,
        "critical": 15
    },
    "format": "{capacity}% {icon}",
    "format-icons": ["", "", "", "", ""]
},

The bug only occurs when the full-at option is specified, and the formatting also displays as if the battery is dead (i.e. it triggers the critical threshold).

An error should be printed can you run waybar in the terminal and print the output here?

It's happening right now, running waybar spawns a second bar with the same issue but unfortunately no relevant errors are printed (the width one is always printed):

With -l trace:

Any chance of a point release with this included? Or is it full steam ahead to 1.0 now?

When I undock I'm resorting to catting /sys haha. And yesterday I forgot to plug in and the laptop of course died. Perma 0% is a challenge 😛
