WireMock - invalid content-length after modify body by ResponseTransformer - wiremock

Question

I'm trying to modify response with wiremock in record mode.
I'm extending ResponseTransformer and replace an absolute url reference.
Wiremock returns modified response but doesn't update Content-Length header so chrome thinks there is few more bytes to download.
When i try add Content-Length header by :
...
Response.Builder.like(response).headers(updateContentLength(response.getHeaders(), modifiedBody.length()));
...
private HttpHeaders updateContentLength(HttpHeaders headers, int bodyLength) {
HttpHeaders newHttpHeaders = HttpHeaders.noHeaders();
for (HttpHeader header : headers.all()) {
if(header.key().equalsIgnoreCase("Content-Length"))
{
newHttpHeaders.plus(new HttpHeader(header.key(), bodyLength +""));
}
else
{
newHttpHeaders.plus(header);
}
}
return newHttpHeaders;
}
Some headers like Set-Cookie disappears
and "Transfer-Encoding: chunked" is added extra.
using:
wiremock-standalone-2.14.0.jar

1) The bug is reporoted here github.com/tomakehurst/wiremock/issues/907
2) My workaround is to not change actual content length by adding white characters in a place where a client ignores them e.g.
<script src="https://example123456.com/aaa"></script>
replace by:
<script src= "https://example.com/aaa"></script>
