Constrained fields don't work as supposed to when using numeric field special function expressions on Transform Component's Scale field on multiple GameObjects at the same time

Reproduction steps:

1. Open the attached “BugTest1.zip” project
2. Open the “Assets/Scenes/SampleScene.unity” Scene
3. Select all of the Cube GameObjects in the Hierarchy window
4. Enter “L(1,5)” into the Transform Component’s Scale’s 'X' field
5. Observe the Cube GameObjects in the Game View

Expected result: All of the Cube GameObjects have their ‘X', ‘Y’ and ‘Z’ Scale values equal to one another (The GameObjects retain Cube shape)
Actual result: The 'X’ Scale value is not “1”, but 'Y' and ‘Z’ Scale values are set to “1”(Some of the Cubes turn into Cuboids)

Reproducible with: 2021.3.16f1, 2022.1.24f1, 2022.2.2f1, 2023.1.0a25
Couldn’t test with: 2020.3.44f1 (“Constrained Proportions” option is not available)

Reproducible on: Windows 10 (21H2)
