QA for 0.1.18 release

[aatmanvaidya]

We changed the Show Slur Metadata to add a feather blur over the word instead of the icon.

There are two bugs to fix

1. a small error I see on Firefox, in some words, when I hover over them, the metadata key's are not in bold, while in some words they are -- this is only happening of Firefox

in some places its correct

and in some places its not

I was able to fix it my adding a style like this instead of using the <b> tag. I don't know if its a robust solution

style="font-weight: bold;"

2. Sub-words inside a word are also getting identified, should this be fixed?
