Details:

The latest version of SDL3 has replaced SDL_SetTextInputRect with SDL_SetTextInputArea. SDL_SetTextInputArea also takes an extra parameter for cursor (the offset of the current cursor location relative to rect->x, in window coordinates)

The relevant commit is -

SDL_SetTextInputRect() has been renamed to SDL_SetTextInputArea()
The new function includes the cursor position so IME UI elements can be placed relative to the cursor, as well as having the whole text area available so on-screen keyboards can avoid it.

This is used in imgui_impl_sdl3.cpp on line 154.
