Opening plugin UI disables active automation in Ableton Live

[justmull]

Observed Behavior:
When opening the plugin UI during playback, Ableton Live instantly disables active parameter automation lanes. The DAW behaves exactly as if a parameter was manually adjusted by the user, terminating the automation playback and illuminating Live's "Re-Enable Automation" button.

Minimum Reproducible Example:
This behavior can be reproduced from a new project without any scripts.
Create a new HISE project.
Add a single UI Slider (Knob).
Enable isPluginParameter for the knob.
Export as a VST3 / AU.
In Ableton Live, configure the parameter, draw automation on the timeline, and press play.
Open and close the plugin UI window repeatedly.

Result: The automation lane will eventually disable upon opening the UI.

Reproduction rate: With a simple 1 knob UI, the failure rate is approximately 1/30 attempts. It may depend on the rate of change of the parameter. With a complex UI (60+ parameters) the failure rate is approximately 1/3 attempts.
