In calendar weeks formatting, the ISO "weeks" tag {:%V} has no effect

[tjavdar]

In format the tag {:%V}is admissible but has no effect. That is, the readout of week numbers on the bar and the pop-up calendar differ by 1:

  "clock": {
      "format": "{:%a, %b %d, v.%V | %H:%M}",
      "calendar": {
         "locale": "sv_SE",
         "format": {
           "weeks": "<span color='#99ffdd'><b>{:%V}</b></
         },
       },
  }

This config on:
waybar 0.10.4-2 (Arch)
Linux i5 6.10.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 27 Jul 2024 16:49:55 +0000 x86_64 GNU/Linux
LANG=en_US.UTF-8

IMHO, the readout of "weeks" for {:%U}, {:%W} and {:%V} should match the one from the corresponding shell command:

   `date +%U`
   `date +%V`
   `date +%W`
