Wrong input takes value when moving from one <input> to another <input> (each <input> in <iframe>)

Short description of the problem:

If <input1> inside <iframe1> has the focus and iOS autocorrect suggestion comes up (word gets highlighted in blue), focussing on <input2> in <iframe2> and typing results in data appended to input1 instead of input2, even though cursor is on input2.

iframe1 and iframe2 have the same src.

What behavior are you expecting?

User Input is shown in the right element .

Steps to reproduce:

Type input in first input of page, waiting for the iOS keyboard autocorrect.
Once autocorrect suggests a spelling fix (example: typing Grt might suggest Get as the correction) tap on next input.
Type something in the second input
