### Bug fixes

Fix an infinite loop when the match position of a `RegExpCursor` ended up in the middle of an UTF16 surrogate pair.

### New features

The `literal` search option can now be set to make literal queries the default. Move out of surrogate pairs when tracking match position in RegExpCursor

The new `searchPanelOpen` function can be used to find out whether the search panel is open for a given state.
