Punch through bug causes activation of a lower layer object instead of the visible object. Textbox can move to evade text input. Most prominent on facebook, probably poor programming on their part, maybe to a non complied (by other browsers) standard. 2 very annoying, problem bugs

Screenshot 1 is from a podcast where tapping pause or skip can unexpectedly activate the episode behind the floating bar, leaving the desired episode. This could be improper markup or style on the part of talkstreamlive dot com or a Firefox flaw. Screenshot 2 is from the bug ridden kingdom of Facebook. Entering a comment or reply can be a nightmare. I workaround using the address bar for scratch then cutting, returning if facebook doesn't leave, and pasting, avoiding the squirrelly behavior avoiding input attempts. This is almost certainly their fault, IMHO. Perhaps Mr. Selfenfull could benefit from some guidance. The comment textbox floats above the previous comments by others, appears to be related, and may after all be a Firefox bug. Desktop Firefox has no problem. Thanks and good luck.
