TextToolbar contains option "Strikethrough" twice though one is actually option "italic"

[marcelwgn]

Describe the bug

A clear and concise description of what the bug is.

The TextToolbar in the sample app has two buttons that announce themselves as "strikethrough", though one of them is actually the option "italic".

• Is this bug a regression in the toolkit? If so, what toolkit version did you last see it work:

Steps to Reproduce

• Can this be reproduced in the Sample App? (Either in a sample as-is or with new XAML pasted in the editor.) If so, please provide custom XAML or steps to reproduce. If not, let us know why it can't be reproduced (e.g. more complex setup, environment, dependencies, etc...)

Steps to reproduce the behavior:

1. Open TextToolbar page in sample app
2. Hover over 2nd and 5th button
3. Observe that both say "strikethrough" though the first of the two actually is the italic button

Expected behavior

A clear and concise description of what you expected to happen.
2nd button should have "Italic ctrl+i" as tooltip text.

I can't repro this specific issue with the text in debug builds of the sample app, so I think this was fixed. Or are there any differences between the store version and the debug builds of the app? (Closing this issue in the meantime)
