1901126 - Table border overflows off the start edge of its container (potentially being clipped), with 'border-collapse: collapse`

Status: VERIFIED FIXED

(Core :: Layout: Tables, defect)

Description

[Daniel Holbert [:dholbert]]

Attachment: testcase 1

STR:

1. Load attached testcase (based on dshin's "generalized case" attachment in bug 1434366

EXPECTED RESULTS:
Black border should not be covered up. (The black-bordered area should be large enough to contain all of the colorful borders inside of it.)

ACTUAL RESULTS:
Black border is covered up.

Gecko/WebKit give ACTUAL RESULTS. Blink gives EXPECTED RESULTS. Blink is probably correct per dshin's analysis in bug 1434366 comment 12.

Attachment: Bug 1901126: Invalidate along the entire table edge when a cell in the edge of the table is modified. r=#layout-reviewers

Resets were added due to issues that statefulness brings (See Bug 1871609).
When a table-edge cell is modified, the resultant table-edge border width
may or may not be depemndent on that cell (As an unmodified cell could
have the maximum border width).

Depends on D213792
