Bug 30148 – Applying h1 format to text node after HR tag fails to include first letter of text node.

• Component: HTML Editing
• Status: RESOLVED FIXED

[Michael Thomas]

STEPS TO REPRODUCE:
1. Go to midas demo: http://www.mozilla.org/editor/midasdemo/
2. Enter the following HTML: '<hr>test'
3. Place the cursor after the word 'test'.
4. Select 'Heading 1' from the menu.

RESULT:
The heading style is applied to the entire line except the first character:

<hr><h1><span class="Apple-style-span" style="font-weight: normal; font-size: medium; ">t</span>est</h1>

EXPECTED:
The heading style is applied to the entire line:
<hr><h1>test</h1>

The patch on bug 32131  fixes this test as well.  It's another case where we call applyStyle then restore the selection incorrectly.  In this case, we're off by a character so the selection no longer contains the first letter after the HR tag.

I think this bug is now fixed, but we should add a layout test so it doesn't regress.

We could make this a js test and add more test cases.

Huh?

Wrong description here.
