Short description of error

On any new file, Driver Property Data for Texture Particle System won't appear visible in Graph Editor/Drivers when is set only 1 driver.

Exact steps for others to reproduce the error

I create a subdivided plane with applied scale. Create static particle system from it, I want to control particle density with a Texture/ Gradient.
After I'm creating a new texture within the particle system. From there I set first Texture to Blend/Ramp black and white - from where the properties after RIGHT CLICK add
DRIVER/manually are not appearing as a captured data visible in the Graph Editor... even the operation is not registered in the Toggle System Console.

However I play a bit, and The DATA is appearing, and it's showing up in the Graph Editor - only when, I create 2nd Driver for any the the Particle Influence Tab.
After I create the 2nd driver, any new one is appearing correctly withing the same Particle Texture Properties Section - visible for controlling in the Graph Editor!
