MacOS - Window resizes when switching tabs

Hi There,

This has caused minute-by-minute frustration for a long time (feels like years!). And while I can find threads discussing it, I can't find an answer so thought I'd check-in to see if thre's a fix.

Steps to reproduce

1. MacOS 13.6.3 (had this issue in previous versions as well)
2. Photoshop 2024 25.3.1 (had this issue in previous versions as well)
3. Application Frame –> Off
4. Zoom resizes Window –> Off
5. Open a document and resize the window to the desired size (so there's space around the document)
6. Open another document and notice how the window resizes to fit the second doc?

Question

Because the documents are tabs within the same window, can't both documents simply centre within the window, with neither document changing the size of the window? 

Sorry if missing something basic, any help much appreciated.

Cheers, Ben
