Setting "Number of results" to 0 for "Select (Active tags)" form widgets doesn't show all available terms in the drop down. But according to the description of the setting it should: "The number of suggestions that will be listed. Use 0 to remove the limit."
Setup a term reference using the "Select (Active tags)" widget for the form display. Set "Number of results" to. Go edit a node and see that the dropdown stays empty.
Set the "Number of results" in the form widget to anything above 0 and the limit will be applied correctly.
It's an issue with the frontend javascript, so fix the code in active-tags.js.

Thank you @berliner for reporting this issue and suggesting a solution!
The issue was in the frontend JavaScript and has been fixed in 1.0.x-dev (updated on 6 Dec 2024). Setting "Number of results" to 0 now correctly shows all terms in the dropdown.
Could you please test the latest development version and let me know if everything works as expected? Your feedback is always greatly appreciated!
