Issue has been unearthed while converting these two tests from applet to manual main based.
As per the test instructions, it was supposed to print 3 copies of window followed with LWC components print. But when "xor" is set to true, it doesn't print 3 copies instead print only 2 copies with second page having issues where some components do not print correctly in XOR mode.

Overall there are two issues when xor mode is set
1. Doesn't print correct number of copies.
2. LWC components don't get printed.
