translation lines break "pause at end of page" setting

[roedoejet]

I was recently informed about this bug and have reproduced it below. If translation lines are present, and the user selects "Pause at the end of page", that functionality is broken. Without translation lines, the pausing happens, but with translation lines, the readalong plays through as normally. It doesn't seem to matter if the translations are displayed or not.

Reopening this issue here because we'll need to update the bundles here to make sure we incorporate the fix in single-file HTMLs generated in the CLI too.

See ReadAlongs/Studio-Web#578 for the S-Web issue that's going to be fixed by ReadAlongs/Studio-Web#579
