System Information
Operating system: Windows 10
Graphics card: GTX3090

Blender Version
Broken: 3.2.0 onwards
Worked: 3.1.2

Caused by b1908f2e0b

Short description of error
When selecting a bone in weight painting mode via ctrl+left click, you can select bones, HOWEVER, if the bone is behind any part of the mesh, (even with Viewport Display: In Front selected), the mesh gets selected instead of the bone.

Expected behavior: I should be able to select the bone, not the mesh.

This worked in versions prior to 3.3.

NOTE: This CAN also happen with octahedral bones, but it is much more sporadic.

Exact steps for others to reproduce the error

Open attached .blend file
Disable the GPU Depth Picking option in {nav Edit > Preferences... > Viewport > Selection}
Select the octahedral armature on left, then the associated cylinder and enter weight paint mode
CTRL+LClick the 3 bones, (these may not display the issue in question, as octahedral bones only sometimes show the issue)
Now repeat steps 3-4 for the armature+cylinder set on the right
See that you have trouble selecting any bone that is occluded by the mesh.

Attached is a .blend file and video demonstration.

Thanks for the report. I'm not able to confirm this in both 3.3 and 3.4
Can you replicate it with factory prefs?: {nav File > Defaults > Load Factory Settings}

I can replicate the problem if I disable the GPU Depth Picking option ({nav Edit > Preferences... > Viewport > Selection})
Disabling that option, the object Cylinder.001 is deactivated (instead of the bone being selected).

I didn't get the notification for this, my bad!

But yeah, I just confirmed it today with the same option. I had GPU Depth Picking turned off for performance reasons (it's pretty bad when you have a lot of bones in a complex armature).

EDIT: Updated working/broken versions based on testing with this config option.

Committed fix which prioritizes pose bones in [weight-paint + pose-mode], (not just pose-mode).

Although its unclear how paint modes should deal with re-selecting the already active object.
It's mostly a redundant action however as it can de-select other objects, that impacts weight-paint + pose mode.

Here are two other fixes I looked into:

P3287: exclude the active weight paint object from selection.

Prefer to avoid this as it may have wider implications for picking objects (using data selector for example).

P3288: conditionally disable re-selecting the active object (restore old logic but only for weight-paint mode).

Works well but adds back complicated logic for a feature that is already supported in pose mode.

If re-selecting the active paint object is ever an issue, something similar to P3288 could be added back, however I'd like to see evidence it's needed.
