Change in Find dialog behavior with Mission Control spaces in macOS Tahoe 26.2

Steps to reproduce

To reproduce, open a MacVim window in one Mission Control space, use Command+F to open the "Find" dialog, then open a second MacVim window in another space and use Command+F to open the "Find" dialog for the second window. On my system, macOS jumps back to the first space and opens the "Find" dialog for the second window in the first space. When a search term is entered into the "Find:" field and the "Next" button is pressed, the search is performed in the second window, but macOS stays on the first space with the "Find" dialog.

Expected behaviour

The expected behavior is that when the Command+F is pressed on the second space, the "Find" dialog would open in the current second space rather than the first space. This was the behavior in the past.

Logs and stack traces

Vim and MacVim configuration where issue is reproducable

No response

How was MacVim launched?

• by launching MacVim.app in macOS (by using the Dock, Spotlight, or the open command)
• by running mvim/gvim in the terminal

Issue has been tested with clean configuration

• by running mvim --clean (or gvim, supplied by MacVim distribution). You can also use the File → "New Clean Window" menu item within MacVim.
• by running vim --clean (in terminal, supplied by MacVim distribution)
• by running vim --clean (in terminal, other suppliers, e.g. /usr/bin/vim)

Reproduce el comportamiento con mvim --clean abriendo ventanas de MacVim en espacios separados de Mission Control e invocando Command+F. Traza el comportamiento del diálogo Find a partir de esa reproducción; se considera terminado cuando el diálogo se abre y permanece en el espacio actual mientras busca en la ventana correcta.
