[BUG] Position mismatch (offset) at the client after moving or flipping

[Oxy949]

Module Version: v2.9.3

Describe the bug
After the actor appears on the stage, his position is synchronized between clients, i.e. everyone has the lower left corner of the portrait in the lower left corner of the screen. However, if you modify the position of the portrait, including flip (using mouse), the gamemaster's one stays fine, but the clients' portrait now has a permanent offset.

If you look closely at the debug screenshot, you can notice that the portraitContainer (XPos / YPos) has changed, however original picture has not moved. After the first change, the offset exists until actor dismissed.

My module settings:

• allow control: gm only
• max portrait size: 700px
• Others: default

To Reproduce
Steps to reproduce the behavior:

1. Launch a world with a gamemaster and a player. They must be logged in from different devices to reproduce the issue.
2. Create a new character, change the character's theatre portrait to png 2048x2048px
3. Set allow control: gm only, max portrait size: 700px in module settings
4. Show any actor on stage, it should appear on client
5. Move actor on stage or flip, now the client's version of the actor have an offset

Expected behavior
The client's version of the actor must be consistent with gamemaster's one
