Status: RESOLVED DUPLICATE of bug 790475

Steps to reproduce:

Started typing a word. Partway through hit the [Backspace] button to correct an error, then finished typing the word correctly.  Followed this word with [space] and another word.
- For example: typed the word "excellent"
- Hit the backspace key to delete the last three letters, now appears as "excell"
- Re-typed the last three letters, so word now reads "excellent"
- Completed the sentence, now reads something like "excellent wine"



Actual results:

Spellcheck underlined in red only the part of the word typed after hitting [backspace], as if this portion of the word was being interpreted as a stand-alone misspelled word. 

Right-clicking on that half of the word gave suggestions for how to correct only that group of letters that had been typed after the [backspace] key was hit.  If the correction is selected, it's appended to the start of the word, making a truly misspelled word.

Using the example above:
- The word appears as "excellent" with spellcheck's red squiggly underline only underneath the last 3 letters, "ent"
- Right-clicking on that part of the word gives suggestions for how to correctly spell "ent," e.g. "net," "sent," "rent" etc.
- Choosing one of these suggested corrections appends that word onto the start of the original word creating a new non-word, which is itself flagged as a misspelled word, e.g. "excellnet"



Expected results:

Spellcheck should recognize the entire word as spelled correctly.

I would be happy to download beta, but just want to double check that all of my current emails and folders will transfer over correctly, the same way they would with a standard version update...?
