Description
When I send HTML containing <span style="font-size:0.5em"> some text </span> to the HTML Purifier, it trims the 0 and returns <span style="font-size:.5em">. The html without the zero then does not work well with our other technologies. Is this trimming a wanted behaviour? Would it be possible to skip trimming of the zeros?

Research direction
Start by reproducing the issue with the reported input and trace how HTML Purifier processes the font-size style value. Done means determining whether the leading zero should be preserved and, if so, confirming the output retains 0.5em without breaking purification.
