a simple image of bug reproduction

SUMMARY

i've had this bug when i switched from version 3.* (sorry i don't recall) to version 4.1.7, i had an animation file with a music audio in it, the audio was generally mute when i worked, but today when i unmuted it, the selected animation doesn't work, instead it continues until the music hands.
i also created a whole new file and reproduced it with the steps below, and it occures.

STEPS TO REPRODUCE

1. create a new file, swith to animation workspace and create few frames (6 for example)
2. add an mp3 audio file (i don't know if it should be longer than the animation or not)
3. UNMUTE the audio
4. select a marge of the frames to be played by selecting from the timeline panel, or setting a marge in the animation panel (for exemple select only the first 3 frames of the 6 we have : 0-> 2)


OBSERVED RESULT

krita will just ignore the marge of frames you give, and instead plays all the frames and continues to the end of the sound file.

EXPECTED RESULT

the animation should only play on the designated frames and ignore the length of the sound, the sound also should stop at the last frame and get back to the beginning at the first frame.

SOFTWARE/OS VERSIONS
Windows: windows 7 32bits

ADDITIONAL INFORMATION

- the audio file is in mp3 format.
- the original file had 215 frames.
