Thanks a lot! That is the trick.

This is not a bug. It occurs because you are including the line ends in your folded ranges, so for example the start of line 29 is folded away, causing its contents to be added to line 1. You can do this instead:
cm.markText({line: 1, ch: 0}, {line: 28}, {inclusiveRight: true, inclusiveLeft: true, collapsed: true});
This will collapse only the text you actually want to hide. You have to make the mark inclusive on both sides to actually have it hide the line. Also, when I just tested this I noticed a bug that caused codemirror to not update its display in this case. This patch fixes that.

I want to hide lines 1-28, 30, 31, 33, 34, 35, and 39. I want to keep lines 29, 32, 36, 37, 38, 40, 41, 44, and 45. After I run through each line setting the markText, the correct lines appear, but the line numbers are 1, 30, 33, 37, 38, 39, 41, 42, 45.
It appears the line numbers get messed up somewhere around the lines that are hidden/collapsed.

In what way are the line numbers wrong?

I'm trying to use markText with collapsed=true to hide lines that contain certain text. The correct lines get hidden, but the line numbers are wrong.
I am trying to hide the lines by setting "from = {line: lineNumber, ch: 0};" and "to = {line: lineNumber+1, ch: 0}".
If I try to set "to = {line: lineNumber, ch: <length of line+1>", the line disappears, but the collapse does not happen.
Any ideas?
