[bug]: The width of the DateTimePicker changes unexpectedly

[rktyt]

What version of design-system are you using?

@strapi/design-system@2.0.0-rc.18

What's Wrong?

The input width changes depending on whether the clear button is present.

To Reproduce

https://design-system.strapi.io/?path=/story/inputs-datetimepicker--base

Expected Behaviour

The input width does not change due to any actions.

Thanks @rktyt. We'll try to look at it as soon as possible. (cc: @lucasboilly this is probably due to the xs IconButton that is now used for the clear button)
