This only affects chrome and also does not appear to cause issues for date/time inputs. While weird that this pseudo is the one used for a datalist marker it is indeed correct.

This PR tweaks the dropdown arrow added to an input by Chrome when it has a
listattribute pointing to a<datalist>.Right now the arrow isn't centered vertically:
The cause of this is the line height being inherited into the pseudo element which controls how the marker is positioned. I think this is because it's being drawn with unicode symbols but I'm not sure. It could just be from the
list-itemdisplay.After this PR changes the line height its centered again:
Some notes:
This only affects Chrome and also does not appear to cause issues for date/time inputs. While weird that this pseudo is the one used for a
<datalist>marker it is indeed correct.Fixes #18499
