Cannot find frame when "intoElement" field of PictureElement is in an iframe

[bhecquet]

Scenario to reproduce:

private static FrameElement frame = new FrameElement("report frame", By.id("myframe"));
private static Table testlist = new Table("Integration tests", By.className("table"), frame);
private static HtmlElement testRow = new HtmlElement("test row", By.tagName("tr"), testlist, 0);
private static PictureElement lastState = new PictureElement("laststate", "ReportPage/images/laststate.PNG", testRow);

public ReportPage openLastState(String testName) {
    lastState.click();
    return this;
}

Expected result:
Picture is found

Current result:
Error with "frame not found"

Other context information
May be due to the fact that multiple searches are done inside the frame, and when selenium searches the "intoElement" testRow, its context is already in the frame
