Theme navigation duplicated after "composer upgrade"

[kdim95]

Laravel framework version: 9.36.2
Aimeos Laravel version: * 2022.07.2
PHP Version: 8.1.9
Environment: Linux

The main menu appears to be duplicated after executing the "composer upgrade" command.

Before the issue appeared, I've been changing around some theme settings.
I was attempting to create a theme with a new name in my extension.
I copied the default theme with a different directory name and then added the config client/themes/mytheme/MyTheme, so the theme appears in the dropdown, switching to that theme caused the main menu to disappear, I also attempted to switch the "Shop domain" setting to "mytheme", then there was an error and I had to switch it back to "default".
I also attempted commands to clear the cache after adding the theme, "composer upgrade", "php artisan cache:clear", "php artisan view:clear".

I have a backup of the old public/vendor/shop/themes/default.
When I replace the files in that directory with the ones from the backup, the issue is fixed.
But every time I execute "composer upgrade", the issue returns.
It appears that there is a mismatch with the version of ai-client-html the package, because my backed up theme files have slight differences, for example the "aimeos.css" and "aimeos.js" files.
This leads me to believe that the "ai-client-html" package was somehow upgraded and is not working well with the rest.
It seems to be overwriting my theme files when I execute "composer upgrade".
What should I do to fix this? The main issue seems to be the duplication of the menu items.

I fixed it by overwriting vendor/aimeos/ai-client-html with the one from my backup, I don't understand what went wrong here, but the issue seems to be fixed now.

Don't change any files in the ./vendor/ directory because they will be overwritten each time a new version is installed using " composer update"!

Instead, create a Laravel theme extension and adapt the files there:
https://aimeos.org/extensions

I think I wasn't changing the files in the ./vendor directory, but they somehow updated.
I could have touched a few lines and reverted the changes in the package, but that was just to make sure I was overriding the correct files in my extension. Could that have caused the package to update somehow?

I have created a theme extension, but the issue persists when I switch to the new theme.

Steps to reproduce:
1) Create a mytheme Laravel theme 2022.x extension here:
https://aimeos.org/extensions
2) Upload the theme to packages/mytheme
3) Execute composer update
4) Switch to the new theme from the settings

If not switched to the new theme, there are no errors.

Bumping because the menu issue persists, not sure what's causing it.

Tested locally but unable to reproduce.
According to your screenshot (browser inspector), there's also no HTML node twice.
There's only something in the background which looks like a shadow of the navigation.
