Describe the Bug

The last word of a paragraph sometimes ends up in the indented quotation that follows it. The same EPUB displays correctly on android/desktop with different apps

For example, this structure:

<div>Their hypothesis was remarkably straightforward:<div class="quote"><i>If an MBA education...</i></div></div>

renders with the introduction ending at remarkably, followed by an indented straightforward:If an MBA education...., straightforward: should stay in the introduction.

The word is still in partWordBuffer when the nested <div> starts a new text block. The following <i> flushes it into the quotation instead of the preceding paragraph.

This patch flushes the pending word before starting a block. It adds regression tests for nested quotations and headings. Both fail without the fix, and all 41 parser tests pass with it. I also checked before/after renders and confirmed the fix on my device after clearing the book cache.

This looks closely related to CrossPoint #519, which fixed the same behavior for <br/>.

The patch still needs a layout-cache version bump so existing books pick up the fix without manual cache clearing.
