'''This is the correct behavior!''' The assumption is if you plug in the headphones (left plugged in) you don’t want the internal speakers to also be active. This is how most PC’s work, and how all Mac systems work. My TV’s and stereo also work this way.
Here’s a closer look on how the headphone jack works

The simple act of plugging in the plug breaks the short to the internal speaker lines.
If you want an either or both speakers with the headphones plugged in you’ll need to get your self a pair of wired (using either the headphone jack or USB plug) or wireless Bluetooth speakers (with the headphone jack you’ll need a spitter). You’ll then need to manually to enable which you want on. With Bluetooth the menu bar can be used.
Your other Mac systems must have either method I just described or they had there headphone jack modified

=== Update (08/23/2019) ===

The iMac’s are not setup to offer switchable outputs via the Speaker/Headphone jack only one output is possible.
+
+
To gain dual output which you are active at the same time you’ll need to do this externally with a dual headphone adapter connected to external speaker & headphone devices
+
+
You need to use either a USB DAC adapter or via Bluetooth with your sound gear connected to it which you can then use the sound control panel to switch the output between the internal speaker/headphone set and the external via USB connected gear.

This is the correct behavior! The assumption is if you plug in the headphones (left plugged in) you don’t want the internal speakers to also run. This is how most PC’s work, and how all Mac systems work. My TV’s and stereo also work this way.
