Using hints why is the line breaking in the first instance but not the second?

[electricanki]

In this first instance the line keeps breaking when I reveal the hint but not in the second instance. The problem is with this part of the code {{#词繁体字}}[{{hint:词繁体字}}]{{/词繁体字}} - is there a way to over come this?

(1 FIRST INSTANCE)
