System Information
Operating system: Linux-5.8.0-7630-generic-x86_64-with-debian-bullseye-sid 64 Bits
Graphics card: AMD Radeon RX 5700 XT (NAVI10, DRM 3.38.0, 5.8.0-7630-generic, LLVM 11.0.0) X.Org 4.6 (Core Profile) Mesa 20.2.1

Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-01-18 14:02, hash: 023ebb890b
Worked: (newest version of Blender that worked as expected)
(I had this issue since 2.91.0 already)

Short description of error
The 'Modifiers' tab disappears when selecting 'All' in the Graph Editor, however. when deselecting 1 single channel (for example X Location) and selecting it again. The 'Modifier' seem to be tricked and will appear.

Then when applying a modifier with multiple channels selected, it will only apply to the last selected channel. The only way to apply a modifier to All desirable channels is to:
(See steps to reproduce the error)

Exact steps for others to reproduce the error

{F9596885}- Select 1 channel (i.e. X Location)

Apply a modifier (i.e. Cycle)
Hit the 'copy modifier' button (within the Modifier tab)
Select all channels. ( the Modifier tab will then disappear)
Deselect 1 channel, and select it again to make the Modifier tab reappear.
Hit the 'paste' button to apply the Cycle modifier to all channels.

[Based on the default startup or an attached .blend file (as simple as possible)]

Not sure I understand correctly:

modifiers tab [same as FCurve tab] show the active Fcurve (and the modifiers on the active FCurve
modifiers are only added to the active FCurve [you can paste to all selected though] -- this is the same as for object modifiers, no?
if you have no active FCurve/channel (by deselecting all), no modifiers are shown

This all seems to be working as designed?

However, there are things that are inconsistent with how this works for objects:

deselecting all keyframes [in the main region of the Graph Editor] will keep an active FCurve
deselecting all channels {key A} in the channels region will clear the active FCurve
selecting all channels {key A} in the channels region will clear the active FCurve

Dont think the last two are neccessary @dr.sybren?

This is consitent with objects; you can have an active object without having any object selected. This is debated in #82359.

deselecting all channels {key A} in the channels region will clear the active FCurve

selecting all channels {key A} in the channels region will clear the active FCurve

The first one IMO is fine because there is no visual indication of which is the active FCurve anyway. We're trying to push for a "nothing selected means nothing active" approach, but that's discussed in #82359.
The second one doesn't really make sense to me, though, and looks like a bug or at least a design flaw.

yup consistent doesn't mean it's good.

i think the last 2 you mentioned A to deselect clearing the active one is good., but not clearing when selecting all channels.
