<p dir="auto">Soft wrapping breaks apart completely and creates a big mess if a certain sequence of actions is performed. I'm on OSX 10.8.4 and Atom 17.0.</p>
<p dir="auto">To reproduce:</p>
<ol dir="auto">
<li>Start Atom, open a blank new file, and turn on soft wrapping</li>
<li>Enter text until it wraps to the other line:<br>

<li>Your cursor being at the end of line 1, press ENTER to go to the next line. This correctly creates a newline character and moves the cursor to the beginning of the next line:<br>

<li>Press BACKSPACE. This deletes the new line that was just created and correctly moves the cursor back to the end of line 1. Screenshot same as in step 2:<br>

<p dir="auto">So, the first "virtual" line was duplicated. Also, this duplicated first line is now non-selectable and non-editable -- I can't even put my cursor there (it's frozen).</p>
<p dir="auto">DevTools console doesn't show any errors.</p>
<p dir="auto">Sometimes you have several files open in a window and two or more of the tabs share the same file name (e.g., subfolders of examples with many index.html files). Just like Chrome and Sublime (and perhaps other OS X apps?), when you hover of the tab for a couple seconds, we should show additional context. In this case, the full path to the file.</p>
