Papa's Pizzeria: Transition interrupts not emulated correctly

[InputEvelution]

Describe the bug

When clicking on another station in Papa's Pizzeria, the screen will briefly fade to grey, and then fade to the new station. During this period, it's possible to click on another station again (either the same one the game's already transitioning to or another one entirely). Currently there are two issues with the implementation in Ruffle:

• Clicking on a station while the screen is fading into grey has absolutely no effect. The game will instead continue to commit to the current screen transition.
• Clicking on a station while the screen is fading out from grey will cause the transition to get glitched, sending the player to the new station immediately with no fade whatsoever. In older versions of Ruffle (such as 2022-11-28), Ruffle would successfully start fading in to grey, but then skip over the fade out.

These specific issues can most easily be tested via the usage of an auto-clicker script, but programs such as libTAS can provide more precise control over inputs.

Expected behavior

• Clicking on a station while the screen is fading into grey should cause the screen transition process to restart from the beginning.
• Clicking on a station while the screen is fading out from grey should not be able to work.
