Reproduction steps:
1. Open the attached “IN-109924.zip” project
2. From the Project Window, open the “RecipeTest.uxml” in UI Builder
3. In the Hierarchy, drag the #Component" element across the children elements of #RecipeContainer
4. Observe the UI Builder Viewport

Expected result: The element is not overly stretched
Actual result: The element is overly stretched

Reproducible with: 2023.1.0b1, 6000.0.54f1, 6000.1.14f1, 6000.2.0b12, 6000.3.0a3

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

Notes:
- If #Component is outside the #RecipeContainer, it will stretch the elements vertically, and if #Component is inside the #RecipeContainer, it will stretch the elements horizontally
- When dragged outside #RecipeContainer or on the #Component itself, sizes return to normal
- The more the element is dragged over the elements, the more stretched they become (the stretch builds up)
- Any element dragged along the #RecipeContainer children will yield the same result
