Does a PF2e spellcaster who takes multiclass dedications into other spellcasting classes, and related spellcasting feats, gain more spell slots?

Ezren is a level 10 evocation wizard, and hence would have spell slots of the following levels:

+-------------+-----------------+ | Spell level | Number of slots | +-------------+-----------------+ |           1 |               4 | |           2 |               4 | |           3 |               4 | |           4 |               4 | |           5 |               4 | +-------------+-----------------+ 

However, at level 2 Ezren took the Sorcerer multiclass dedication. At level 4 he took Basic Sorcerer Spellcasting, and Bloodline Breadth at level 8.

How many spell slots does Ezren have in a given day? Is it:

+-------------+-----------------+ | Spell level | Number of slots | +-------------+-----------------+ |           1 |               6 | |           2 |               6 | |           3 |               6 | |           4 |               4 | |           5 |               4 | +-------------+-----------------+ 

Because at level 8, spellcasting archetype feats grant an additional spell slot of first, second and third level, AND the bloodline breadth feat increases each of these by one?

Or do these sources of spell slots not stack for some reason? Coming from fifth edition, a wizard who multiclasses sorcerer still has the same number of spell slots as a pure wizard, so I’d like to clarify my understanding here.
