There are a few issues with how NVDA works with html5 form controls.

Datalist: TAB to it or ARROW and ENTER to enter focus mode, arrow to value, and try to switch to browse mode (requires several presses of ESC, where it should require one)

Radiobutton: R to it, status is unchecked, ENTER on it will change to checked (NVDA reports it correctly), but pressing ENTER on it again will not change value to unchecked.

Combobox: C to Combobox, NVDA will read "Select Element, Combobox";
UP ARROW to "type='color'";
DOWN ARROW to combobox;
ALT+DOWN ARROW to expand;
DOWN ARROW to next value;
ALT+UP ARROW to close combobox (NVDA will force combobox to expand) ;
Will have to try ALT+UP ARROW two more times (total of three) to close combobox.
Arrow to it, Expand with ALT+DOWN ARROW, DOWN ARROW to an item, close with ALT+UP ARROW (NVDA will force combobox to expand again)
have to close it several times.
