Suggestion box is misplaced when text is deleted

[TunaYagci]

If you type something and delete, the cursor remains in the last word, hence the suggestion box positions itself to a wrong place.

Try writing a long text. Then open the mention box with @. Then delete the whole sentence. Put another @. There, mention box is misplaced.

It's better show with a GIF:

2 problems are found on a quick debug,

vue-mentionable/src/MentionableTextarea.vue

Line 169 in b507626

if (listWidth > 0) {

1. This line is not working as expected. listWidth is most of the time coming 0.

vue-mentionable/src/MentionableTextarea.vue

Line 167 in b507626

let coords = getCaretCoordinates(this.$refs.textarea, index);

2. Also textarea-caret co-ordinates are not getting updated correctly.
We will have to look for a replacement of these lines or figure out why it is not working properly..
