Attachment: screenshot: view -> use style -> none

You don´t need an extension to disable style, you can do it from the View menu:
Use Style -> none

With Style: none the caption 'Vragen' is seen, though it has style display:
none

The <thead> is shown same width as <tbody>, the column titels 'Naam' through
'verplicht' are sitting right at top of their column, having same width as the
column below. Also the titels are bold and underlined.

Attachment: screenshot: View -> Use Style -> Default Style

CSS enabled: View -> Use Style -> Default Style

Caption 'Vragen' not seen, as it has style display: none,
heading 'Naam' through 'Verplicht' has shorter width than the columns below.

the added row is added with short width, disabling style shows it with normal
width, reenabling style width stays normal, but width of the <th>s returns to
short width.

I see this, but your testcase makes it hard for me (also on little sleep) to
comprehend what the intended (both author and spec-wise) styling is.  I can tell
there is one form of a bug here (at least toggling between style:none and
style:default shows that much).

I am not confirming until I (or someone else) can tell exactly what the bug is
though.

So the basic issue is that there are two table row groups (or rather a table-header-group and a table-row-group) that are kids of a block.  I guess we should wrap them in a single table in that case.  That code is really not as good as it could be...

In any case, not styling your table as a block is the way to go here.
