Reproduction steps:
1. Open the attached “2022.3_Test_Mask.zip” project
2. Open the “SampleScene”
3. Enter the Play mode
4. Click on part of the button that is above the red Image in the Game view

Expected result: The whole button is clickable
Actual result: Part of the button, that overflows from the red Image, is not clickable

Reproducible with: 2021.3.35f1, 2022.3.20f1, 2023.2.10f1, 2023.3.0b7

Reproducible on: Windows 11
Not reproducible on: no other environment tested

Note:
- Disabling the “Rect Mask 2D” Component on the “Mask” GameObject allows the whole button to be clickable, however, the button Image has the “Maskable” property unchecked, therefore it should work both ways
