iframe find highlights look out of place

[jrieken]

Testing #127173

The find highlights in iframes look out of place because they use different colors.

I know this is tricky because Window.find is used but maybe the hiliteColor-command https://developer.mozilla.org/en-US/docs/Web/API/document/execCommand#commands can be used?

Can you provide a gif demonstrating what part of the highlighting looks off?
Also, for both iframe and webview search, we are currently using Electron APIs, rather than window.find.

The colors are wrong, compare with the find colors in text ediors
