Test case

Per CSS 2.1, 17.5 Visual layout of table contents:

Point 3: "The first column box may be either on the left or on the right, depending on the value of the ’direction’ property of the table."

Point 5: "The [cell] rectangle must be as far to the left as possible [...] and the cell must be to the right of all cells in the same row that are earlier in the source document. [...] (This constraint holds if the ’direction’ property of the table is ’ltr’; if the ’direction’ is ’rtl’, interchange "left" and "right" in the previous two sentences.)"

All other browsers consistently interpret the "row propagation" direction to be the table's 'direction'. WebKit has an old bug where the row-group direction is used instead.

Note: Some of the test cases from bug 87900 were based on the assumption that our behavior was fine and would need to be updated. It's probably better to wait until bug 79272 is solved to update them though.

I am able to reproduce this bug in Safari Technology Preview 152 using attached "test case" and the lime color test cases does not show up on the left side while purple on right.

Just wanted to share updated testing results. Thanks!
