Sequence diagram group too wide when containing activations using teoz

Question

Using teoz, if a group contains messages without activation, the group gets a reasonable size with some horizontal padding around the lifelines (see Group 1 below). But if the messages have activation, the group gets some strange extra padding on the right side of the lifeline (see Group 2 below).

This is with v1.2024.0beta3.

Example:

@startuml
!pragma teoz true

group #ffa Group 1
    Particpant_A -> Particpant_B
    Particpant_A <- Particpant_B
end

group #ffa Group 2
    Particpant_A -> Particpant_B++
    Particpant_A <- Particpant_B--
end
