[css-text] test depending on undefined behavior

[frivoal]

Unless I am misunderstanding something, word-break-break-all-inline-010 seems to depend on undefined behavior. https://drafts.csswg.org/css-text-3/#line-break-details says:

For soft wrap opportunities defined by the boundary between two characters, [...] which elements’ line-break, word-break, and overflow-wrap properties control the determination of soft wrap opportunities at such boundaries is undefined in Level 3.

Based on that, the behavior expected by the test is allowed (it assumes that the at the start of the span break is controled by the span), but keeping 3 characters on the first line would be allowed too (assuming the break at the start of the span is controlled by the parent div).

The test should be changed to count as pass in both cases (probably using two references, and only showing red if it fails to wrap at all, or if it wrap between the first and second character of the <div>
