PowerApps for Teams: Broken items in ComboBox

I am enjoying my journey through the half-baked world of PowerApps within Teams (which if you haven't realized yet is a completely different thing than just building a normal PowerApp and linking to it within Teams).  The bad layouts, then limited choices, the awkward redesign of the base UI.  It all makes me so very happy.  Or not.

Today Microsoft has shown me that they aren't beyond failing at simply displaying the values in ComboBox for a hard-coded Collection.

Simplified Multi-Item Editing / Patching

Microsoft's methods for Patch(), Update(), and UpdateIf() make it somewhat stupid when it comes to editing/updating records en masse.  Trying to pull this off can get convoluted if you aren't careful.

This is an example method for taking a Gallery where you display/edit multiple items at once and then save them all as a part of a single command.
