layout: Let `TableSlotCell` store an `IndependentFormattingContext` by Loirooriol · Pull Request #42778 · servo/servo

Loirooriol · 2026-02-23T13:25:57Z

TableSlotCell was storing the BlockFormattingContext and the LayoutBoxBase in separate fields. Now it will store an entire IndependentFormattingContext in a single field.

In particular, this fixes the issue that TableSlotCell::repair_style() wasn't calling BlockFormattingContext::repair_style(). Now we can just rely on the correct IndependentFormattingContext::repair_style().

Testing: Adding a new test
Fixes: #42777

✨ Try run (#22309276646) succeeded.

`TableSlotCell` was storing the `BlockFormattingContext` and the `LayoutBoxBase` in separate fields. Now it will store an entire `IndependentFormattingContext` in a single field. In particular, this fixes the issue that `TableSlotCell::repair_style()` wasn't calling `BlockFormattingContext::repair_style()`. Now we can just rely on the correct `IndependentFormattingContext::repair_style()`. Signed-off-by: Oriol Brufau <obrufau@igalia.com>
