[Tex2002ans]

See attached EPUB.

I copied/pasted 2 lorem ipsums and added a split marker in the halfway point.

Version: Sigil 0.9.13
OS: Windows 10 (1809)

Steps to Reproduce Bug

1. Tools > Reports > HTML Files. You should see Part1.xhtml as ~63 KBs.

2. Go back to Code View and Split at Markers (F6).

3. Refresh the Report.

You'll see Part1.xhtml is ~63 KBs while Part1_0001.xhtml is .01 KBs.

Expected to see both files ~31.5 KBs.

After saving and run/refresh the report again, the file size adjusts fine.

PS. Never ran across this before because I constantly press Ctrl+S like a fiend, so never have unsaved EPUBs. :P
