Why does Safari still show legacy Tiles, and Chrome doesn't?

using the states view, I can still see my Tiles (custom card html import) but Chrome doesn’t show these any longer (already for a while)

I know html import are deprecated, en have disabled that in the frontend.yaml. That setting doesn’t make any difference btw, so not sure what the effect of that setting is…

Thing is if it shows as beatifully in Safari, then why wouldn’t it be possible to have that in Chrome too?

#javascript_version: auto

themes: !include_dir_merge_named frontend_themes

#extra_html_url:
#  - /local/custom_ui/state-card-custom-ui.html
#  - /local/custom_ui/state-card-tiles.html
#  - /local/custom_ui/state-card-value_only.html
#  - /local/custom_ui/custom-weather-card.html
#
extra_html_url_es5:
  - /local/custom_ui/state-card-custom-ui-es5.html
  - /local/custom_ui/state-card-tiles_es5.html
  - /local/custom_ui/state-card-value_only.html
  - /local/custom_ui/custom-weather-card.html

inspector Chrome:

inspector Safari simply loads these, which is rather nice:

Noob question here as I’ve had some issues with chrome (my default), you have cleared the cache … ?

haha, yes, of course . never forget to do so, and reloaded. Also used the refresh dots top left menu.

seems not all browsers react the same way to the same settings in frontend.

other example:
Since javascript_version is marked as deprecated, I commented it out in my frontend.yaml. It immediately makes my customize icons ineffective. Again in Chrome.

so, apparently not (yet) deprecated, or at least not for all browsers, which are all modern browsers (on a Mac with latest updated MacOS )

even the import html seems to still be of some effect. Firefox needs it for the legacy Tiles, while without the regular html imports (so not the es5 imports) it too doesn’t show the legacy states Tiles.

so, the question in the topic remains unanswered…

Well it was a wild stab in the dark.
It does seem like very strange behaviour.
My chrome was updated a couple of days ago (no idea when before then) but if it’s misbehaving, then it supports a lot of people who prefer safari.
Sorry, I’m out of my depth otherwise.
