Extra spaces added when pasting from the web

[pidgin at alexoren.com]

When I paste text into Pidgin, some spaces in the text are doubled.

For example:

Copying the following text from https://news.slashdot.org/comments.pl?sid=14962134&cid=59279246

The rich by far pay more in the total taxes collected that the middle and lower classes, even if the tax rates are off. This is because they earn more of their income through things like stock (which is taxed differently than regular income). There are many reasons for this, and they are not loopholes: Tax income is treated like investment income because it is subject to risk.

And pasting it into Pidgin produces the following text:

The rich by far pay more in the total taxes collected that the middle  and lower classes, even if the tax rates are off.  This is because they  earn more of their income through things like stock (which is taxed  differently than regular income).   There are many reasons for this, and  they are not loopholes:  Tax income is treated like investment income  because it is subject to risk.

Note the extra spaces between the words "middle" and "and", "they" and "earn", "taxed" and "differently", and so on.

When I view the source of the web page, the extra spaces are not present:

	<div class="commentBody">
		<div id="comment_body_59279246"><p>The rich by far pay more in the total taxes collected that the middle and lower classes, even if the tax rates are off.

If we are talking about Medicare for All, that won't be paid for by increasing taxes on the rich.  Instead, we'd most likely be looking at tax rates in France or Scandinavia where they effective tax rates are around 40%.   Let's see how popular that messaging is.</p></div>

This problem happens consistently.

Looks like a bug to me.
