Hi Jamshed Ahmed,

If possible, could you attach the exact HTML that you used as a test case?

You can use the Attach New File button and specify that your file type is an html page.

Here is an example of the html.

1. The first line the numbering starts fine
   • test
   • indent more works fine
2. indent less jumps to 3 as you can see in this line
3. numbering has skipped 2
4. once again trying to indent more
   1. this time with numbers instead of bullets
   2. lets indent more one more time
      • with bullets
      • now trying indent less
   3. one more time
      • test33
   4. indent less againgoes back to 2 instead of 4 as you can see in
      this line
   5. indent less again
5. From 5 it goes back to 3..... as you can see in this line.

When I forward the same html email to my work address, the output is fine. However, in firefox, it shows messed up as explained.

This is how I see it in my firefox browser. However, when I click show original, it seems to show fine

The format is pretty easy to be messed up after doing some indent more and indent less on both Chrome and Firefox. I can reproduce this on Firefox actually. However, perhaps we need to know how Gmail implements these commands.

If this is a bug in Gmail, we could close this later. Confirmed this for now.

This may be duplicated by Bug 1548753. Indenting more/less may insert/remove <ul>/<ol>. This causes a complicated nested structure. I'd like to mark this as dup for now.

This wrong markup is caused by html editer execCommand("indent") bug of Bug 54479

(In reply to Alice0775 White from comment #10)

This wrong markup is caused by html editer execCommand("indent") bug of Bug 54479

Thanks for clarifying this. I change the dup bug number.

However, maybe both Bug 54479 and Bug 1548753 have impact on this, so I use See Also to link Bug 1548753.
