Hidden (via hideturtle) receive click events

Repro steps

I reproed this with Boxer 3.4.19 2024-06-24

1. Download, unzip, and open hidden sprite repro.box.zip
2. Click the middle of the graphics context. There's a large hidden (via hideturtle) rectangular sprite there

Actual result: The output box updates to say "Clicked sprite". This indicates the sprite's mouse-down-on-sprite handler has run. This is unexpected since the sprite is hidden

Expected result: The output box remains empty. The sprite's mouse-down-on-sprite handler hasn't run because the sprite is hidden.

Here's a screenshot of the repro file:
