Parenting a non-visible ScreenGui into PlayerGui on Client Init and then enabling it later will break all automatic sized GuiObjects

(sorry for long title)
I’ve noticed a very specific bug where parenting + enabling ScreenGuis will not trigger Automatic Sizing updates properly.
Here’s the repro

  1. Have screengui somewhere outside of playergui like replicated storage
  2. have screengui not visible (enabled = false)
  3. have an object with automatic sizing inside of it
  4. have a localscript on startup that will move the screengui to playergui
  5. wait a bit of time (ex: 1 second)
  6. enable that screengui
    Result: Automatic Sized object is broken:

Additional note: This bug will only occur if the re-parenting to the playergui occurs immediately on startup.
If you were to add a task.wait(1) before parenting and enabling the screengui, the bug will no longer occur

Video:

Repro Place (contains 1 screengui and 1 localscript) :: (run as client with F5):
AutomaticSizingBug.rbxl (59.6 KB)

Workaround:
Any code that reparents a screengui to playergui at the start of Client Initialization just needs a task.wait(1) before re-parenting the screenguis and it should be fine
