Bug ID: 196337
Summary: Strange scrolling issue on Safari 12.1 & 12.2 when
display: none & display:block is used.
Product: WebKit
Version: Safari 12
Hardware: Macintosh
OS: macOS 10.14
Status: NEW
Severity: Critical
Priority: P2
Component: Scrolling
Assignee: webkit-unassigned at lists.webkit.org

Example Video
With the release of 12.1, we began getting reports of strange scrolling behavior.
This JSFiddle should demonstrate the issue:
https://jsfiddle.net/blackoctopus0/7f56qx9c/2/
Hovering over a "message" in the example above will utilize the following CSS style:
.message:hover .message-span {
display: block;
}
Doing so causes the scrollable div to scroll up. This is undesired. Utilizing a framework like Vue can also cause this. Utilizing v-show. This function toggles elements using display: block/none;
Please feel free to contact me with further questions. See attached video from the above fiddle.
