I do not know if I have missed something (again).

I was editing an ePub yesterday The html was awful (stupidly convoluted) and I was simplifying it. As I was going through the "stylesheet", I noticed a lot of the defined styles were identical except for their names.

My immediate thought was "Doesn't the Removed Unused CSS Rules" fix this". I had run it on opening the ePub so I knew the option to Merge Identical CSS Rules option was ticked.

To check matters I created a dummy ePub which had several dozen pairs of styles which were identical except for their names. I also created an empty paragraph for each CSS style addimg class="dunnystylename" so each style was mentioned in the text.

I then ran the plugin. NONE of the identical CSS styles was merged.

I then repeated the operation with the Merge box unticked (just in case) and got the same result.

Has this feature been depreciated, is it a bug or is it my setop?

I am on Windows 10 Enterprise - 64bit, calibre version 5.1
