Today I found a irritating bug to which I haven't found where to report so I add it here.

The bug is that if you have created a table and then adds widths to the cells those set widths are automatically removed if you goes to view the article and then if you ever saves it again at any way.

I assume the feature is still a thing as it is described how you add widths in the documentation. For those that doesn't know:

If you write e.g: that cell is given 20% of the entire width of the table. Quite handy if you want it to look good.
