System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 980 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 2.91.2, branch: master, commit date: 2021-01-19 16:15, hash: 5be9ef4177

I'm not sure when the last time it worked was, but I know it was broken in 2.91.0 as well.

Short description of error
Sometimes you must modify the strength of a texture field to apply prior changes to the texture type.

Exact steps for others to reproduce the error
deps_graph_bug.blend

Open the blend file. You will see 100,000 vertices each with a hair, and a texture field. DON'T MODIFY THE LAYOUT
In the lower right panel, the texture type starts out as "Image or Movie".
Change the texture type to "Clouds".
Take note that the hair doesn't update yet.
In the texture field panel just above, change "Strength" from 1.000 to 0.900.

OUTCOME
Only after changing the "Strength" does the hair update to use "Clouds". Changing the texture to "Clouds" does not update the hair.

EXPECTED
The hair should respond to changes in the texture type without modifying the "Strength" to trigger it.

IMPACT
Working with texture fields lacks some of the fluidity of other force fields, and has high potential for confusing users.
