current color not showing when pressing next/prev button

[abid-sayyed]

fix:

change the below code:

from:

for (let i = 0; i < results.length; i += 1) {
const r = results[i];
const className =
i === resultIndex
? ${searchResultClass} ${searchResultClass}-current
: searchResultClass;
const decoration: Decoration = Decoration.inline(r.from, r.to, {
class: className,
});

to:

for (let i = 0; i < results.length; i += 1) {
const r = results[i];
const className =
i === resultIndex
? search-result-current
: searchResultClass;
const decoration: Decoration = Decoration.inline(r.from, r.to, {
class: className,
});
