Hello all,

While viewing an email in Gmail default mode, blank lines are inserted once a second.

Does not happen in Chrome (Version 88.0.4324.182 (Official Build) (64-bit)).

Version 1.20.103 Chromium: 88.0.4324.152 (Official Build) (64-bit)

An update: Happens only when vertical scroll bar is top top of view, i.e., if the vertical scroll bar is moved to bottom of page, insertion of lines stop.
