The hacks are for the legacy our behavior, such as using ASCII white-space for the trailing visible white-space and making it visible with following <br>. However, once we start to use   without the <br>, we don't need the hacks anymore.

Attachment: Bug 1947106 - Make the hack for bug 1938110 and bug 1940278 run only when we use the legacy white-space normalizer r=m_kato!

The hacks are required only for the other legacy behavior which uses ASCII
white-space even before a block boundary but with a padding <br> element.
Therefore, once we use the Blink compare behavior, it'll put an NBSP without
a padding <br>, we don't need them anymore.
