[Widgets] Incorrect behaviour when using Website Shortcut Widget

Steps to reproduce

1. Ensure Website Shortcuts (Top Sites) are visible (2-8 sites with favicons).
2. Add the Firefox “Websites Shortcuts” widget on iOS (Today’s widget/Home page widget).
3. Tap on the shortcuts shown in the widget.

Expected result

Firefox’s widget loads consistently and shows the same sites, order, and favicons as Home Page Website Shortcuts

Actual result

It loads Firefox but displays the last tab the user interacted with.

It seems to be related to the commit 4f80d54, specifically for devices iOS 18 and above. I believe this property is the issue widgetAccentedRenderingMode(.accentedDesaturated). I can take a look at this issue if is ok.
