A11y: Page hangs chrome while loading

Project Member Reported by dsexton@chromium.org, Nov 2

Issue description

Chrome: 72.0.3595.2 (Official Build) dev (64-bit) (cohort: Dev)
JAWS: 2018
NVDA: 2018.3.2

Steps to repro:
WARNING: this will hang chrome and possibly the screen reader, save your work and read all steps before continuing
# With a screen reader on, visit https://wiki.cockos.com/wiki/index.php/Action_List_Referenceh.htmL
# Try to navigate with arrows
# Read the title with insert+t to check when Chrome hangs

Expected: Chrome loads and the page is easily navigated with arrows 
Works as expected in ChromeOS and Firefox

Actual: Chrome hangs for a few minutes and does not respond to input, but usually recovers without an error message

Try to open this page in Chrome browser, only 5 MB long HTML file, on Android phone with TalkBack enabled - completely hangs Chrome, the only thing one can do is kill it when the "app not responding" message appears. Happens to any long page, maybe for 512 kB you would wait a minute and it would recover, but it is still unacceptable. Firefox on Android under TalkBack on the same page works perfectly and instantly...

This is completely unacceptable behavior and should be fixed asap. Thanks.

IMPORTANT: Please add OS: Android to this bug as well. Thank you!
I also prepared a shorter test, just 500k of HTML. This time Chrome with TalkBack under Android 9 (Pixel 2 XL) does not lock for so long, but seriously misbehaves nonetheless. It takes very long time to react to screen taps, then executes in short bursts several earlier taps. Completely unusable. Compare with Firefox, which still works great in this case. Here is a link to the shorter test page:
