Interesting. Nice find @AdriGamer. Let me tag in @Mattches so he’s aware.
Mattches, I was able to test as they mentioned and the issue occurs both on Nightly and on Release.
For example, I typed in the a, went to other tab, came back, changed a to b and submitted. The search came back as results for a. Then tried where typed in somewhere, tabbed, swapped back, changed somewhere to something and submitted, but the results given was for somewhere.
Also doesn’t seem to matter which search engine used as happened both with Brave and Google as default search.
