The info pane can display a Chemical Plant's status as [Stopped, Output full] instead of the correct status [Stopped, Fluid ingredient Shortage].

Steps to produce:
1 Build a single Refinery crafting Basic oil processing.
2 Build a Chemical plant crafting Sulfur.
3 Connect Crude oil to the Refinery's input
4 Connect the Refinery's Petroleum gas output to the Chemical plant's Petroleum gas input.
5 Connect water to the Chemical plant's water input.
6 Power both the Refinery and Chemical plant.
7 Hover mouse over the Chemical plant.
8 Wait for one Sulfur to be crafted.
9 The UI is correct when Sulfur's stack size is reached.

What happened:
The info pane will display the Chemical Plant's status as [Stopped, Output full] while waiting for more Petroleum gas, and while the output slot contains some sulfur (but not a full stack).

What was expected to happen:
The info pane should display the Chemical Plant's status as [Stopped, Fluid ingredient Shortage] while waiting for more Petroleum gas and the sulfur is not a full stack.

Occurrence:
This always happens.

Version 2.0.76 (build 84451 expansion, win64)

Thanks for the report however this is correct. The output full is not related to the stack being at maximum capacity but related to 2x the machine recipe output.

Why is this the case?
It seems strange to me to reference the output when the halted status is due to the input.
Would it not be more helpful / more accurate to say [Fluid ingredient shortage]?

There is no shortage, the entity is full once the output slot holds 2 or more times what the recipe creates.

I think I understand now.
In that case, why does my chemical plant not stop until it crafts 50 sulfur (stack size), instead of 6 sulfur (recipe yield * 2) ?
