[css-text] Shaping for break-all/word-break

Two people read the text differently, so the clarification appreciated.

Both word-wrap/overflow-wrap: break-word[1] and word-break: break-all[2]
say:

> Shaping characters are still shaped as if the word were not broken.

and

> When shaping scripts such as Arabic are allowed to break within words due
to break-all, the characters must still be shaped as if the word were not
broken.

One read these text as after a word was broken, each broken part is
reshaped as if it is a word.

The other read as after a word was broken, the reshape must not occur.

Which is correct?
