Is it a bug that clicking will pause the music?

When we play the generated music in BIAB, but we click MIXER or other content, the music will pause for one second. Have you noticed?
I think this is very strange. We are listening, why does it pause?
Is this normal? I have never encountered this situation in any other DAW.
