Why form submit opens new window/tab?

I found a lot of questions "How to open form result in new window", but I'm facing opposite problem.

I have form:

<form:form method="post" commandName="search">
    ...
    <input type="submit" value="Search" />
</form>

Then I have controller with handling method

@RequestMapping(value = "/search.form", method = RequestMethod.POST)
public String submit( @Valid final SearchObject searchObject, final BindingResult bindingResult ) {
    if ( bindingResult.hasErrors() ) return "forms/search";
    return "redirect:/A/result.form";
}

Everything works fine, except the fact that result is opened in new window/tab.

Solution that I found and is working is to add target attribute:

<form:form method="post" commandName="search" target="_self">

But _self is default AFAIK.

I'm wondering why is that happening.

I checked generated HTML and it seems to me ok:

<form id="search" action="/myApp/A/search.form" method="post">

Problem was in base tag. I had intentionally target="_blank" in tag, probably because I copied the example from w3schools :-/
