Magento 2.4.6-p13 template hints don’t work on frontend

What can be the reason that hints are not displayed on frontend? I did clear cache with:

php bin/magento cache:clean; 
php bin/magento cache:flush; 
rm -rf generated/*; 
rm -rf var/cache/*; 
rm -rf var/page_cache/*; 
rm -rf var/view_preprocessed/*; 
rm -rf pub/static/frontend/*; p
hp -d memory_limit=2G bin/magento setup:static-content:deploy -f;

Mode is developer, I ran this successfully:

php bin/magento deploy:mode:set developer

I set in admin template hints to ON, in admin.
I set in admin no URL parameter for hints (so that it should display always, regardless of whether there is the template hints querystring or no).
I set template hints for default config, default store default website, all. I removed all stuff (see above terminal commands).
In admin I cleared magento cache
In admin I flush cache storage.
I refresh the browser frontend page (CMD + SHIFT + R). The hints are not there. What else can be the reason?
