| 21 /** Test for correct ExpectEndProperty calls in CSS parser **/ | |
| 22 | |
| 23 /* | |
| 24 * Inspired by review comments on bug 378217. | |
| 25 * | |
| 26 * The original idea was to test that ExpectEndProperty calls are made | |
| 27 * in the correct places in the CSS parser so that we don't accept | |
| 28 * garbage at the end of property values. | |
| 29 * | |
| 30 * However, there's actually other code (in ParseDeclaration) that | |
| 31 * ensures that we don't accept garbage. | |
| 32 * | |
| 33 * Despite that, I'm checking it in anyway, since it caught an infinite | |
| 34 * loop in the patch for bug 435441. | |

| 44 * tested. | |
