Unwanted linebreaks in nested List

[sapaya]

Using tinyMCE v4 with worpdress 4.9.7 here.

When pasting a nested List as a HTML, there are extra
Tags added before the child list, like so:

<ul class="pageitem accordion-menu">
    <li class="accordion-menu"><a class="accordion-child" href="#">Parent Link</a><br />
      <ul class="accordion-menu-sub">
        <li class="acc-sub"><a href="#">Link</a></li>
(...)

fix_list_elements and forced_root_block are turned off in the editor settings.

Hi,
I'm having difficulties with reproducing your issue. What are you pasting from? Browsers? See if you can reproduce this on a fiddle. http://fiddle.tinymce.com
Thanks!
