Comment (by adamsilverstein):

 I also spent some time trying to reproduce this issue without any luck.
 Tried renaming plugin name, folder name, capitalizing, adding spaces, etc.
 In all cases the data-slug identifier matched the returned slug and the
 plugin was marked as updated.

 If the problem persists, it would be great to have clear steps to
 reproduce @caraffande! Thanks.

 > Can you elaborate on the '''exact''' steps you're using that shows the
 problem still? (including filenames & plugin headers). Furthermore, is
 this plugin using a 3rd-party update script or WordPress.org updates?

 > The testing I've done is using a mixed-case folder names & filenames to
 duplicate, I set it up using the following:
 > {{{wp-content/plugins]$ mv akismet/ aKISmet && mv aKISmet/akismet.php
 aKISmet/aKISmet.php && sed -i 's/3.1.3/3.1.0/' aKISmet/aKISmet.php}}}

 > Looking at your report closer though, I'm somewhat confused.. You seem
 to be indicating that you've got uppercase characters in the slug field,
 which isn't supposed to be possible here.
 > It does appear that two different sanitization methods are being used -
 `sanitize_title()` by the plugins page generation, and `sanitize_key()` by
 other code.. but as far as I can tell, for our purposes they should pretty
 close to one another.
