Spaces missing in Paste with Turndown powerpack

[michaelgmcd]

Spaces near highlighted elements (bold, italic, code, strikethrough, etc.) are missing when pasting with the turndown plugin enabled. I've confirmed that this is not a bug with Turndown by pasting the same html into their example

See reproduction below:

Can't reproduce in Firefox 61.0 / Chrome Beta 68.0.3440 (Windows)

This could be related to Clipboard API on your OS. To investigate, run this in demo page's console, then paste something into HyperMD editor:

editor.setOption('hmdPaste', (html) => console.log(html))

I'm running Chrome 67 on a Mac. When copying a section of the HyperMD readme, I get the following HTML on paste:

I'll investigate this a little further.

I'm guessing that the <span> </span> blocks are being stripped out with my OS/browser

I cannot reproduce this problem in Chrome Version 69.0.3493.3 (Official Build) dev (64-bit) on my Mac. At the same time, Safari cannot reproduce it, either.

Would you like to try a newer version of Chrome?

[michaelgmcd]

Will do!

Was waiting before my next Chrome update before updating here. This is still an issue on Chrome Version 68.0.3440.75 (Official Build) (64-bit) on my Mac High Sierra (10.13.6). I will leave this open until the Chrome version that @nasyxx mentioned is the latest stable build available.
