Issue while importing questions, which have the same question text, from a question pool to an assessment

There is an issue while importing questions, which have the same question text, from a question pool to an assessment.

1. Create a question pool with 2 questions which have the same question text:
i.e:

Question1 (Multiple Choice type):

Question text: "My question"
Label A: "Option A"
Label B: "Option B"

Question2 (Short Answer/Essay type):

Question text: "My question"

2. Create a new assessment.

3. Copy all pool's questions to the assessment using the "Copy from question pool" option.

4. Only one question has been copied because both questions have the same question text.

This bug happens with any question type.

I've attached a mockup up image to clarify this.
