[hbase] Upload data into a cell breaks

e.g. create a new cell, go in editor and upload an image

we get something like "function d()

{if(0<arguments.length)return d.Wa(c,arguments[0])&&(d.X(),c=arguments[0],d.W()),this;a.k.Ob(d);return c}

"

to test with a pdf too.

At the same time, is it normal to be able to inline edit a text cell only once? (second time click just does not do anything)
