`line-height` can't be changed on some epub

[bilogic]

Hi,

On Plato 0.9.34,

1. I changed line-height to a default of 1.5 in Settings.toml
2. This setting has an affect on only some epub
3. I tried opening those unaffected ones in koreader and was able to affect their line-height aka line spacing

Any idea how I can troubleshoot? Thank you.
