Description

We should have testcases that are nested flex containers in many combinations.

Ok, to list this out:

Have a flex container that has children (direct descendants and children of the flex item) that are:

  • table
  • flex
  • grid
  • contains floats

In all of the scenarios above - do so for both flex-direction: row|column and flex-wrap: wrap|no-wrap. Additionally, make sure that the item above on its own is interoperable between browsers before including it, as we only want to be testing flex containing a different layout, not the other layout.

Research direction
First, review existing WPT flexbox tests in the `css/css flexbox` directory to understand the test format and conventions. Then, for each combination listed (table, flex, grid, floats) with various flex direction and flex wrap, create test files that verify correct rendering across browsers. Ensure that the nested layout type's behavior is interoperable before finalizing the test, as specified in the issue. The tests should be placed in the appropriate subdirectory and follow the standard WPT test structure.
