I can duplicate the problem; I’m looking into it now.

That makes sense, as the bug was in some code that condenses CSS by eliminating multiple definitions of CSS properties so that code like this:

body {
  width: 100px;
  color: green;
}

body {
  font-weight: bold;
  color: red;
}

body {
  text-decoration: underline;
  color: orange;
}

turns into this:

body {
  width: 100px;
  font-weight: bold;
  text-decoration: underline;
  color: orange;
}

There are a few properties that are allowed to be defined multiple times, but transition (and -webkit-transition) were erroneously left out of that list.

(1) I tried commenting out a section of code that I thought I would use later. When I clicked “Save Stylesheet”, the comment disappeared, and my work was lost.

Comments getting stripped out is a known issue; it’s on our list of things to fix.

(2) I tried using -webkit-filter, which worked fine in the theme’s stylesheet. When I saved, however, it was deleted. I don’t know why Jetpack would delete perfectly valid code.

You’re right; it shouldn’t have been stripped out. We’ll have it fixed in the next release.
