SameLine Vertical Alignment Wrong after a multi-component group

[atom0s]

Version/Branch of Dear ImGui:

• Version: 1.85 WIP (18411) Latest master as of this post: 0a154b30ad0f628256e3cd61b50ceb0840a1f335
• Branch: master

Back-end/Renderer/Compiler/OS

• Backend: Win32 / Direct3D9
• Renderer: Direct3D9
• Compiler: Visual Studio 2019 (16.10.0)
• OS: Windows 10 Pro (1909)

My Issue/Question:

When using some controls, the alignment of SameLine is not properly vertically aligned. This can be seen in the demo examples included with imgui straight from current master branch.

Controls that I have noticed offhand this happens to:

• Color Editors (ColorEdit3, ColorEdit4)
• ListBox

This can be seen easily under the following of the demo window:

• Widgets > Basic > Scroll down a bit towards the bottom.

Screenshots/Video

The (?) help text is not properly aligned vertically to the other text of the control on the same line.

Standalone, minimal, complete and verifiable example: (see https://github.com/ocornut/imgui/issues/2261)

Use the current demo (Direct3D9) and it can be replicated from stock code.

I believe this is a variation of #4190

The "text baseline" info is held on a per-line basis and Group/SameLine/Group can't really pass it on from one side to another. However in the case of the widget you are pointing out here, it seems like we should be able to come up with a simple fix. I'll look soon.
