As of the current update (v.0.10.1.0) it is impossible to resize the width of the emote-column. Choosing "Size column to fit" or "Size all columns to default" doesn't fix this either.
Small update: changing the size manually of the other columns makes the emote column come back as is intended. This doesn't change the fact that "Size all columns to default" doesn't seem to work as intended.
