Different icon packs for datetimepicker icons (prev+next and input)

[Sogl]

Description

I use free fontawesome icons in my project.
My datetimepicker code:

<b-datetimepicker
    placeholder="Дата публикации"
    icon="calendar"
    :datepicker="{ firstDayOfWeek: 1, dayNames: ruShortDays, monthNames: ruMonth}">
</b-datetimepicker>

In result I see prev and next but calendar icon isn't working:

Console error:

Could not find one or more icon(s) {prefix: "fas", iconName: "calendar"} {}

Because calendar in the regular style (far):
https://fontawesome.com/icons/calendar?style=regular

Ok, when I add pack to my code:

<b-datetimepicker
    placeholder="Дата публикации"
    icon="calendar"
    icon-pack="far"
    :datepicker="{ firstDayOfWeek: 1, dayNames: ruShortDays, monthNames: ruMonth}">
</b-datetimepicker>

Result becomes without prev/next:

Console:

Could not find one or more icon(s) {prefix: "far", iconName: "angle-left"} {}
Could not find one or more icon(s) {prefix: "far", iconName: "angle-right"} {}

Chevrons are in solid state only:
https://fontawesome.com/icons/chevron-left?style=solid

P.S. Of course, I can use one pack of icons, but I do not like the solid version of the calendar icon.

Why Buefy need this feature

User can use different icon packs for input icon and for prev/next icons.

I dont know what would be the better approach for this. Maybe icon props could accept both a string (current behavior) or an object. The object could be used to overwrite default for a specific icon. ex:

icon-pack="fas"
icon="calendar"
:icon-prev="{ icon: 'angle-left', pack: 'far' }"

What do you think? Do you have another suggestion?

I think the option with prev/next icons from different packs is not so frequent. However, it gives more flexibility if somebody need it.
