MATLAB R2016a: char arrays break string escaping, online and offline

[amordoch]

I am using dates as axis labels in the format mm/dd/yy, and I'm storing them as a char array, i.e.:

val =
5/26/18
2/26/18
1/26/18

fig2plotly (offline and online) breaks trying to escape the strings this kind of char array. Seems that this particular case isn't accounted for in charescape(). Using a cell array of strings works normally.

I think a simple fix for this would be to simply check if you have a char array with >1 column, use cellstr(), and continue as normal. Screenshots below.
