Some extra reminder on these tests as I believe 'can record and repla…

…y style mutations' covers more ground.

Could probably emphasize that these 2 are related to `insertRule` i.e. programmatic mutations as opposed to text mutations

-   * This test is to make sure that this problem doesn't regress
-   * Test case description:
-   * 1. Record two style elements. One is recorded as a full snapshot and the other is recorded as an incremental snapshot.
-   * 2. Change the color of both style elements to yellow as incremental style mutation.
-   * 3. Replay the recorded events and check if the style mutation is applied correctly.
+   * the regression part of the following is now handled by replayer.test.ts::'can deal with duplicate/conflicting values on style elements'
+   * so this test could be dropped if we add more robust mixing of `insertRule` into 'can record and replay style mutations'
