Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: Quadro RTX 3000/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.88

Broken: version: 3.1.2, branch: master, commit date: 2022-03-31 17:40, hash: cc66d1020c
Worked: Never

Short description of error
NLA Sidebar tab doesn’t refresh on keyframe creation when first using the NLA and there is no UI change to indicate action selection in the track list so a user doesn't know they need to select it to get to the settings they need. Once they do select it, they have no idea of the current selected state, as there is no UI change to show it is selected/active or not.

Exact steps for others to reproduce the error

Creating from scratch workflow 1 When using the NLA for the first time

Open Blender and change the timeline view to the NLA editor
Hit N or Menu- view-sidebar to show an empty sidebar area
Select the default cube (if you don't have it create a cube) and keyframe the cube. at frame 1 and frame 20
Notice that keyframes are created and selected in the timeline after creation yet the NLA UI side panel remains blank. No update has happened to make the action selected or active.
Also notice that the ACTION is always colored and looks like it is selected but the Theme NLA setting "Source List Text Highlight" doesn't seem to effect the Text on the Action display.
Next click on the object name (Cube or the action name (Cube action) in the left track list of the NLA, Notice that once you do it refreshes and the sidebar panel now shows settings for the current action. Notice that there NO UI change to indicate that after clicking on the Action name in the track list that it has been selected.
#Once you have clicked on it and caused the sidebar to refresh, it never goes away, it doesn't go back to being blank, it always shows the settings.

Suggested fix. The sidebar should refresh to with creation of first key or action, it should never be blank when an object is selected and it has keyframes inserted, starting a new action. The theme should indicate the selected state of the default action track.

There are other issues around the UI but they are more design while this is a UI bug.

This was already reported in #87681 (UI bugs in NLA Editor and Action Editor), which was falsely closed.
Will merge reports and update that other one with additional information from this one.

Well actually, will merge the other one here since the description is spot on here, just dropping my note from the other report:

In #87681#1150543, @lichtwerk wrote:
in regards to Bug 1:

nla_animdata_panel_poll will call nla_panel_context and at this point the (only?) bAnimListElem from ANIM_animdata_filter is of type ANIMTYPE_NLAACTION.

that type is not covered so poll will never be true

investigating ANIMTYPE_NLAACTION atm. to see if just permitting it along the other types in nla_panel_context with be OK (seems to work - but want to be sure)

also would still need to explain the difference between this (ANIMTYPE_NLAACTION) and what happens after clicking header/track (then we also get ANIMTYPE_OBJECT afaict)
