Comment 3 for bug 297193

Ok since this bugreport lacks important information I will try to to add useful information.

reproduce Problem:
- watch an anime with english subtitles
- go to a scene where maybe a Japanese sign is translated via subtitle and a conversation is going or
- go to a scene where there are 2 conversations going - but only the unimportant one is displayed

Problem description:
- only 1 subtitle is displayed
- you may read the signs translation but are not able to follow the conversation as it's subtitles are not displayed as long the signs translation is shown

expected behavior:
- if two or more subtitles are supposed to be shown the same time - every subtitle text gets its own space to be displayed
- this way you can read the signs translation or the unimportant conversation and still follow the important conversation

This is a serious issue as this sort of scenes are very common in most anime. I have included an extracted subtitled where this very situation occurs at 14:49 min. In this scene the teachers dialogue is displayed but the main characters one isn't shown at all.

This one is displayed:
Dialogue: 0,0:14:49.74,0:14:58.29,SD_Overlap,,0000,0000,0000,,{\be1}{\an8}Usually, these can easily be mistaken for one another, so please take care.

And these get dropped
Dialogue: 0,0:14:50.66,0:14:52.78,Default,Saionji,0000,0000,0000,,{\be1}If you have enough time to study from a book,
