Taskbar "Net speed data width" value doesn't work

[e-t-l]

In Taskbar settings, I set the "net speed data width" value to 3 and saved the settings. I would expect that this makes network speeds show as either "123 MB/s" or "12.3 MB/s" or "1.23 MB/s", for example. However, the network speed continues to display as "123.4 MB/s" (i.e. it always shows the 1/10th decimal place).

How can I make the network speed only display 3 digits? (As an alternative, I would be happy if it only displayed integer values.)
