Set line-height same as font size

[mihaliak]

Set x-row line-height same as font-size to fix issues with some fonts on last line of terminal.

This PR should fix #628

UPDATE: removed whole css as chabou said line-height is same as font size as default

[chabou]

Could better to just remove this line. By default, line-height has the same value than font-size.

I don't know why we have this line-height of 1.2em set.
We must be sure to not introduce some regressions

@chabou just removed whole css block for x-row, this should be fine

@chabou @rauchg This was added by @dotcypress for emoji!

@chabou Removing the whole line doesn't fix #628 for me.
Instead I use :

x-row {
    line-height: 1em;
}

[chabou]

You're right, we need to specify 1em to have emoji vertical aligned.
@mihaliak can you update your PR with @mojoaxel recommendations ?

I'll merge it. If it leads to some emoji regression we'll find another way to correct this regression. #628 really hurts

[mojoaxel]

LGTM fixes #628

I think this is 👌 we can fix regressions.
