SM not releasing memory from private window

[Justinh]

For some sites, SeaMonkey doesn't release all the memory for some private tabs.
For example:
- start SM (I'm on 2.53.12 x64, Win10)
- open a private window
- open https://ixsforallph-my.sharepoint.com/: ... Q?e=BnYI94 in it
- close the window
- open about:memory, click "Minimize memory usage" (just to be sure, ya know)
- click Measure - observe that SharePoint site's memory is still being held onto

Is this a bug? It makes me wonder if private windows are even private if all the memory associated with it is not destroyed.

I get a "Something went wrong" with that link (so maybe it is time bombed or whatever).

Anyhow, if you open the same outside of a Private Window, do get the same results (unreleased memory) in that normal window?


Aside from "Minimize memory usage", given time, is the memory eventually released?

The link still works for me.
Home Depot also is an offending site, that I recall. Same with a normal window.

I may or may not understand memory not being destroyed with normal windows, but I do not understand private windows not destroying their objects.
