Description

Reproduction details:

When the configuration contains display.percent.type including ["num", "num-color"], and the format contains a padding (> or <), the output doesn't display correctly.

My guess is that the padding is being calculated not based in the displayed string, but it is also considering the coloring characters.

I tried to find an existing report, but I wasn't able.

Screenshots

I created a small config-bug.jsonc attached below that reproduces the issue.

In the screenshot below, the first Memory module uses {percentage>3} which I expected to be displayed as 84% which are exactly 3 characters. Instead it erases "84%) | 26.02 G" string that was supposed to be displayed.

The second Memory module uses {percentage}, which displays the correct colored number.

Yeah, that's why display.percent.width exists
