Italic with no selection fails to find word

[johndavidpearce]

When the cursor is positioned over/near a word ctrl+b (or Bold button) produces bold as expected:

Hello world|.
[ctrl+b]
Hello |**world**|.

However, ctrl+i (or Italic button) produces error:

[getWordRangeAtPosition]: ignoring custom regexp '\_?[A-Za-z\u00C0-\u017F]*\_?' because it matches the empty string.

Work around: use ctrl+b+b+i or cmd+D, ctrl+i to select word before applying italic.
