Radio Input `other` value is not valid when other_choice is disabled

Running ACF PRO 5.7.1 -

I have a radio field with other_choice set to 0 / off. One of the custom choice values we present is
other which triggers conditional logic on other fields.
If other_choice is set to 0, we'd expect a value of other to be valid or accept a null value. However, this now triggers an error in acf-input.js line 6868.

Uncaught TypeError: this.inputText is not a function at Child.getValue (acf-input.js?ver=5.7.1:6868) at Child.val (acf-input.js?ver=5.7.1:4090) at Child.match (acf-input.js?ver=5.7.1:9416) at Child.calculate (acf-input.js?ver=5.7.1:8637) at acf-input.js?ver=5.7.1:9047 at Array.filter (<anonymous>) at acf-input.js?ver=5.7.1:9046 at Array.map (<anonymous>) at Child.calculate (acf-input.js?ver=5.7.1:9040) at Child.render (acf-input.js?ver=5.7.1:9023)

If the value of the field is set to other, there is an assumption that there is inputText() on the field, although in this case because other_choice is off, there is no inputText.

Start at acf-input.js line 6868 and follow the getValue, val, match, and calculate calls shown in the conditional-logic stack trace. Reproduce a radio field whose custom value is "other" while other_choice is disabled, then verify that the value is accepted or handled as null without the inputText TypeError.
