For the following code <table> <tr><td> text here </td> </tr> <table> Try folding using the - sign at lime 4 (the </td> line). The code folds OK, and it looks something like <table> <tr><td>... </tr> <table> Now there is a + for the folding in front of the <tr>. Hovering it, though, makes it change to -, and clicking it folds the tr tags. The only way to unfold the td tags is to clikc on the folded region. Dealing with deep tag structures makes this folding issue more annoying.
