Attemping to change the "Maximum Amount Extracted per Operation" setting on an extractor on an item pipe (not tested with attractors or filters, or on fluid pipes) does not work properly. The actual behavior ranges from nothing changing upon closing and opening the GUI, to the setting changing by seemingly arbitrary values upon closing and opening the GUI.

The following is the simplest reproduction test case for this behavior:

1. Install an extractor on an item pipe.
2. Open the extractor GUI.
3. Attempt to subtract one from the extract amount by clicking the - button.
   • Observe that the extract amount changes from 4 to 3.
4. Close and reopen the extractor GUI.
   • Observe that the extract amount appears to be 4 still.
