Preliminary State of HTML results

[foolip]

Update: Look at @LeaVerou's comment instead, as that categorization has been done manually and can be trusted to a higher degree.

State of HTML 2023 is still running, but @SachaG has shared some preliminary results for this question:

Which existing HTML features or browser APIs are you unable to use because of browser differences or lack of support?

This is a freeform text question, and the normalized responses so far look like this:

popover_api    248
dialog_element    163
view_transitions    147
not_selector    119
has_selector    103
pwa    76
subgrid    40
web_components    38
datalist_element    35
declarative_shadow_dom    31
at_container    26
animations    25
input_type_date    22
file_system_access    20
temporal    18
transitions    18
aria    17
intl    16
navigation_api    16
shadow_dom    16
css_nesting    15
element_internals    12
grid    12
custom_elements    11
webrtc    11
backdrop_filter    10

Note that not_selector and has_selector are almost certainly overcounted, as "not" and "has" are common words, and the categorization hasn't been manually verified yet. For words that are not common in English, like "popover", I think the results are reliable.

I will comment on the proposals for features that are listed here.

Thank you @LeaVerou! If you see something in the data that doesn't come through in the summarized form, or quotes that especially telling of the web developer need, please feel free to share here or on the relevant proposals.

I've commented on all proposals I could find now. These responses don't have a proposal:

• <dialog> (was in Interop 2022)
• PWAs generally
• Animations generally
• <input type=date>
• File System Access
• Temporal
• Transitions generally
• Intl
• backdrop-filter (edit: now filed as backdrop-filter #564)
