System Information
Operating system: Windows-10-10.0.19042-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.12

Blender Version
Broken: version: 3.0.0, branch: master, commit date: 2021-12-02 18:35, hash: f1cca30557
Worked: version: 2.93.6, branch: master, commit date: 2021-11-16 14:54, hash: c842a90e2f

Caused by b9febb54a4

Short description of error
Hiding all points of a spline in bezier edit mode does not hide the related curve spline

Exact steps for others to reproduce the error

Add a bezier object (like the squigle)
Go into edit mode
Select all the points
Press H to hide
Only the points are hidden but the curve (spline) remains visible

Expected behavior:
5) Both the points and the related curve spline are hidden (as they were in 2.93.6)

Changed status from 'Needs Triage' to: 'Confirmed'

We are talking about individual splines, right?
Blender was never hiding segments afaict.

But regarding the splines, yes, can confirm, will check

@lichtwerk Yes we are talking about individual splines. Blender never did hide individual segments.

Admittedly it would be very nice if you could hide individual segments but lets not turn this into a feature request and fix the regression instead.

Hmm, I think this might be another victim of the ongoing curve code transition. Since curves are drawn in the viewport with CurveEval, which doesn't contain the "hidden" data at all currently.

This is also caused by b9febb54a4

It is in the same ballpark as #93573 (Regression: Selection outline of curves in edit mode)

Changing to High prio, since it is a 3.0 regression

I'm not sure if this is possible to fix without larger changes currently. The evaluated curve has no idea about which control points were hidden in the original curve. There also isn't any "original index" tracking to support some kind of lookup heuristic to figure out what to hide. There is also ongoing discussion about switching to a totally separate curve data structure (#94193), so I'm not sure it's worth the time to rethink the design for this case.

Setting to normal priority as it might have never worked and would require design decisions to be made.

Eh, agree on the other part but yes, it worked prior to b9febb54a4 :)
