For the record, from black-box testing of WebKit a few years ago, it
looked like it normalized the selection after every change. Even if you
called .addRange(), it copied the range and then stuck the selection
endpoints inside a nearby text node if available, etc. I think it's
taking things too far to change script-specified selections, but the
right way to do this is probably to have some sort of helper method in
Selection like NormalizePoint(nsINode*, int32_t) and call it before
every user-initiated selection change. We might want to disallow other
types of user-created selections from occurring in the future, although
my brain is too rusty to supply any.
Do we want to allow a selection like <b>foo</b>{}<i>bar</i>, with the
selection collapsed in between the <b> and <i>? IIRC, WebKit in my
testing forced this to be <b>foo[]</b><i>bar</i> (always making it on
the previous text node). A ten-second test in WordPad suggests this is
the right thing to do.
I don't think any of this has to be in the scope of the current bug,
though.

Title:
composer changes font mid email
Status in Mozilla Thunderbird Mail and News:
Confirmed
Status in thunderbird package in Ubuntu:
Confirmed
Bug description:
Binary package hint: thunderbird
As I'm typing my emails in Thunderbird, I can see what appears to be a
font size change on screen, normally in the second line of text. The
second line appear smaller than the first. It's barely perceptible, so
half them time I think I am imagining it.
Well, I've started Bccing to myself to check, and the emails I am
receiving from myself are not only a different size, they're also a
different font. Composer starts in some default serif, and by the
second line is sans. I'd bee glad to email someone viz thunderbird,
and also send along a screenshot of how it looks while I am typing.
Thanks.
