Matches should work also with multiline strings

[aaltat]

When keyword returns multi line string, like

HOME
Workbox

then

✅ Get Text element matches HOME
✅ Get Text element matches Workbox
❌ Get Text element matches HOME.*Workbox

It would be great if there would be some support out of the box for result strings which are multiline.
