Dictaction - result.success in xAPI statement is always false

xAPI statement example:

actor: {...}
verb: {id: "http://adlnet.gov/expapi/verbs/answered", display: {…}}
object: {...}
context: {...}
result:
score: {min: 0, max: 14, raw: 14, scaled: 1}
completion: true
success: false

Even if result.scale.scaled is 1 the result success is false.

The 'Behavioural settings' in editor have no impact.

Tested with: https://h5p.org/dictation (1st example)
Library version: 1.0.2

This happens because the mistakesTrimmed used in isPassed() is never declared nor assigned a value.

See: h5p-dictation/src/scripts/h5p-dictation.js

this.isPassed = () => this.mistakesTrimmed === 0;

Proposed change:

this.isPassed = () => this.mistakesCapped === 0;
Above change fixes issue for me, but I will live decission upto you. 

The result.success is true or false as expected.
