package 'nav2_msgs::a' not found #111

Description

@jorlynlegarrec

PlotJuggler: 3.13.2
ROS2 distro: Jazzy

When subscribing to any ROS2 action feedback topic, PlotJuggler fails to deserialize the message with the error: package 'nav2_msgs::a' not found
Tested on nav2_msgs/action/AssistedTeleop_FeedbackMessage and other nav2 action topics with the same result. Standard pkg/msg/Type topics work fine.
The error string nav2_msgs::a suggests the type parser is splitting the 3-part type string nav2_msgs/action/AssistedTeleop_FeedbackMessage on / and truncating, rather than correctly resolving the full type.
