None. A WebKit extension.
In Blink, 'results' attribute just adds a magnifier icon to an INPUT field. It's a cosmetic feature.
In desktop Safari, it controls how many submitted queries are shown in a popup opened by clicking the magnifier icon.
This is a WebKit-extension, and it seems no one tried to standardize it.
We'd like to deprecate this attribute in M51, and remove it in M53.
Motivation
It's a WebKit extension.
Interoperability risk
Firefox: Not implemented.
Edge: Not implemented.
Safari: Shipped for years
Web developers: No signals
Compatibility risk
The usage is about 0.04%. However, because this is just a cosmetic feature in Google Chrome, it should be safe to remove it.
Ongoing technical constraints
We had to relax OSX sandbox only for 'results' attribute. See
crbug.com/508935 and
crbug.com/505836. We can avoid this issue by drawing an image ourselves. However, investing in a WebKit-only feature is not reasonable.
Was this feature supported on all six Blink platforms (Windows, Mac, Linux,
Chrome OS, Android, and Android WebView)? Yes or no.
Yes.
OWP launch tracking bug
Link to entry on the Chrome Platform Status
Requesting approval to remove?
Yes.
