Disabled item within scrollable table still responds to keyboard input

[lethal-guitar]

Version/Branch of Dear ImGui:

Version: 1.88 WIP (18717)
Branch: master

Back-end/Renderer/Compiler/OS

Back-ends: imgui_impl_sdl.cpp + imgui_impl_opengl3.cpp
Operating System: Windows 10, Mac OS 10.14

My Issue/Question:

When using a scrollable table, BeginDisabled/EndDisabled within a table cell doesn't prevent keyboard input (ImGuiConfigFlags_NavEnableKeyboard). This only seems to be a problem for the first row.
I experienced this with a checkbox. I haven't checked other widgets, and I haven't tested gamepad input yet.

Mouse interaction is prevented as expected, and this issue does not occur if ImGuiTableFlags_ScrollY is not used.

Standalone, minimal, complete and verifiable example: (see #2261)

if (ImGui::BeginTable("example", 1, ImGuiTableFlags_ScrollY))
{
  ImGui::TableNextRow();
  ImGui::TableNextColumn();

  ImGui::BeginDisabled(true);
  ImGui::Checkbox("Test", &test);
  ImGui::EndDisabled();

  ImGui::EndTable();
}

Thank for reporting! Fixed with 088487a.

As a understand, the issue doesn't have to do with tables or "first row", but it happened when starting navigation inside a window where there are ONLY disabled items. Should be fixed now.

Ah nice, that was very quick! Thank you.

Ah yeah that could be, in my real world example the table had more than one row but all checkboxes were disabled. So it would match that scenario.
