Steps to reproduce the problem:
1. Create a simple page with an input and some content that will make the page tall enough to see a scroll bar when included in a frame

2. Create a page with a frame that uses the page from Step 1 as the src.

3. Be sure that the iframe height is such that there is a scrollbar

4. Highlight existing text in the input using the mouse. Start from the right of the text and drag to select it all and let go outside of the frame or browser window to the left

5. Start typing to replace the highlighted text

What is the expected behavior?
The text is entered in the order that it is typed and the input cursor line will be blinking

What went wrong?
The text is entered in reverse order and the input cursor line is solid

Did this work before? Yes 67.0.3396.79

Chrome version: 69.0.3497.81  Channel: stable
