I'm using Vivaldi 6.2.3105.58 (Stable) on Windows 10 Pro 22H2. When I type a math operation, for example, 13 * 42, in the search bar, rather than returning an answer, I only receive search suggestions. Here's a screenshot of that.
This has proven to be the case for both the extension-managed search and manually-entered search engine, both with and without my token.
When I use Google on Vivaldi, it gives the answer.
When I use Kagi on Firefox, it gives the answer.
The desired functionality is for Kagi on Vivaldi to behave this way as well, it's a major part of my workflow.
