Autocompletion of quoted directories with spaces does cause the / to be out of the quotes

[Removed by request]

I'm using Ubuntu 16.04 with bash 4.3-14ubuntu1 and I'm noticing if I'm autocompleting a directory name (by pressing tab) that is quoted (no matter if there is only a beginning quote or already an ending quote) and has spaces in its name the / gets always set behind a closing quote. This is not the case if the directory name has no spaces in its name as the / is then set before the closing quote or no closing quote is set if there is only an opening quote.
