Copy text from message is inconsistent - sometimes add EOL

When I copy text from many messages (mostly HTML ones), eM-Client adds EOL to copied text.
In addition, every line has added EOL, thus pasted text has two EOLs per line.

In plain text messages and sometimes within first few lines of message (in some messages), there are no added EOLs, which is weird.

I have upgraded client maybe a week ago with some version from few months ago, thus i could not say in which version was no problem with copying.

Version: 7.2.34711
System: Windows 10 1803 (January updates)

Could anyone confirm or not, it is a bug?
