Steps to reproduce:

SM 2.57 - built to comm-esr60 changeset 5822a83963e3.

Composer:
All views are correct initially.

Actual results:

After 'HTML Tags' view is selected, tags continue to be displayed in the Normal and Preview views.

Expected results:

Normal and Preview views shouldn't display tag icons.

This is not happening to me on the latest 2.57 from wg9s.

Yes don't see an error here. Probably fixed by one of regression fixes.

I've tried
seamonkey-2.57a1pre.en-US.linux-x86_64.tar.bz2 2020-04-06 13:06 51M Linux-64
from
https://www.wg9s.com/comm-257/
and still get the problem, as well as with my own build.

The image sequence is from the wg9s build.

Oki let me check later. Did you use a clean profile? If you have add-ons in most of them are broken and can cause all sorts of problems.

No other instance of FF or SM on the system.
Profile newly created on first run.
Included addons - Chatzilla, DOM Inspector, Lightning, Debug - enabled or disabled makes no difference.
No additional addons included.

The 2.53.1 release using that newly created profile is ok.

Can confirm it now No error logged in the console.
