My modification request did not saved a deleted space in a field

I want to delete the space between two words (Port Aventura → PortAventura) in the comments field on this token: N#236916.

My first modification request (id=11366353) has this change in the title and comments, but the comments were not saved. I did not see this bug until the request was validated.

Then I sent another request with only the comments field, but the system return the warning: “You didn't make any modification.”

And then I sent another request (id=11370446) with a cosmetic change in the description, and the change in the comments. Again, the comment was not saved.

I was able to reproduce (with Admin change request, the change is not taken into account) @Xavier @dzmitry.huletski 

Yes, seems to be a minor bug.

If spaces between words are removed from the comment, it is interpreted as no change.

Adding to the backlog. In the meantime, the workaround is to make any other changes to Comments additionally (e.g. add bold, a comma, a period).
