Steps to reproduce the problem:
1. Create two SpeechSynthesisUtterance instances new SpeechSynthesisUtterance("123"), new SpeechSynthesisUtterance("456")

2. Call speechSynthesis.cancel() to remove all utterances from the utterance queue

3. Attach onend event to first of two SpeechSynthesisUtterance instances

4. Attach onstart event to second of two SpeechSynthesisUtterance instances

5. Call speechSynthesis.speak(<first SpeechSynthesisUtterance instance>)

6. Call speechSynthesis.pause()

7. Call speechSynthesis.speak(<first SpeechSynthesisUtterance instance>)

8. Within onend handler of first SpeechSynthesisUtterance 
A. Log speechSynthesis.paused
B. Log speechSynthesis.pending
C. Call speechSynthesis.resume()
D. Call speechSynthesis.resume()

What is the expected behavior?
1. Within onend event of the first of two SpeechSynthesisUtterance instances the "pending" property of speechSynthesis to be true

2. Within onend event handler of first of two SpeechSynthesisUtterance instances when the first of two .resume() calls is made the second of two SpeechSynthesisUtterance instances "text" property to be rendered as audio output

3. The rendered audio output of the second of two SpeechSynthesisUtterance instances to reflect the "text" property of the object: "four hundred fifty-six"

What went wrong?
1. Within onend event handler of one of two SpeechSynthesisUtterance instances the "pending" property of speechSynthesis is false

2. Two calls to .resume() are needed for audio output to occur, where only one call to .resume() should be necessary to resume speechSynthesis audio output

3. The "text" property of the first SpeechSynthesisUtterance instance is output at speakers, instead of the pending second SpeechSynthesisUtterance instance within the utterance queue. Additionally, the output contains words which are not included in the "text" property of the object: "speak one hundred twenty-three slash speak"
