Deprecations and removals in Chrome 69
Chrome 69 also removed the stalled event from HTMLMediaElements. You'll
find the explanation in Audio/Video Updates in Chrome
69 by François Beaufort.
Removal of document.createTouchList()
The TouchEvent() constructor has been
supported in Chrome
since version 48. To comply with the specification, document.createTouchList()
is now removed. The document.createTouch() method was removed in Chrome 68.

The window.confirm() method no longer activates its parent tab
Calling window.confirm() on a background tab will no longer activate that
tab. If it is called on a background tab, the function returns immediately with
false and no dialog box is shown to the user. If the tab is active, the call
behaves as usual.
The window.alert() method was abused by sites for years, allowing them to
force themselves to the front, disrupting whatever the user was doing. There
was a similar problem with window.prompt(). Because these behaviors were
removed in Chrome 64, and 56 respectively, the abuse has been moving to
window.confirm().
