ExtractToDirectory has missing files when working with encrypted zip files which contain directories

[aaronbarak666-art]

Created an encrypted zip file using 7zip with the following structure:

TestDirectory\a.txt
TestDirectory\b.txt

The following code only extracts a.txt:

using IArchive archive = ArchiveFactory.Open(zipPath, new ReaderOptions() { Password = "test" } );
archive.ExtractToDirectory(outputPath)

Zip files without a password, or without directories seem to work ok
Also 7z files work.

This seems to be an issue with ExtractAllEntries, since this test case works on version 0.38.0, when I use WriteToDirectory instead.
This does break again in 0.40.0, because of #900 which made WriteToDirectory use ExtractAllEntries

Can't reproduce on either latest master or with version 0.40.0 using the same code and the following test archive: TestDirectory.zip

Does this only happen with specific zip files? Could you share an example file?

I've tried your file and it did work.
I did manage to reproduce it again with very small text files (one character). Maybe it's connected to the compression method?
Small files are compressed in 7-zip as AES-256 Store instead of AES-256 Deflate
Here's an example for a non-working zip file
TestDirectory.zip
