Subject: [PATCH] Fix: setExtractedText partial span change handling.

ExtractedText represents a partial text change when
partialStartOffset and partialEndOffset are set.
TextView#setExtractedText handles partial updates correctly when text
is changed, but it didn't handle them for span updates when text is
not changed.

Bug: 27635763
