Hi François,
I converted your .epub source file with KindleGen and ran my own tests with pretty much the same results. One footnote behaved differently, though. When I tapped the "V" footnote in your Calibre generated azw3 file, my PW2 displayed the first footnote "(1): the earth." However, when I tapped the same footnote in the KindleGen generated azw3 version nothing happened.

I don't understand this comment. AFAIK, it's not possible to access the Back button while a footnote is being displayed, because as soon as you tap the menu bar area the footnote disappears. And even if a back button was visible, why would readers want to tap it instead of the [x] in the upper right corner of the footnote dialog box??!!

This is to be expected, because mobi7 only supports RTL at a word level. I.e., words are rendered RTL, however, sentences are rendered LTR. BTW, if you embed RTL sequences in texts, you may want to ad a
dir="rtl" attribute to the span or p tags. Otherwise final punctuation marks won't be rendered correctly. (You can see this in Sigil. In your example, the final period is displayed right of the first Alif [א] instead after the last word.)
I did some footnote tests some time ago myself and created a simple epub3 test file with both
epub:type="footnote" based in-chapter footnotes and
epub:type="rearnote" based endnotes that I compiled with KindleGen. Both footnote types are working fine. (KindleGen has partial epub3 support. I.e. epub3 files don't need to be down-converted to epub2 files.)
I'd recommend endnotes, though, because the
aside sections of
epub:type="footnote" based inline footnotes are not automatically hidden (as they are in iBooks), and if you hide them with
display: none nothing will be displayed, if the reader taps Go To Footnotes, and in KF7 books they won't work at all.
If you decide to use both types anyway make sure not to hide in-chapter footnote definitions.
