Text highlight with mouse actions in selenium with java not working - selenium

Question

Using selenium and java, I need to highlight the below text using a mouse click and move, After highlighting, the text I can see another popup and I need to do some validation on that popup.
<h2 class="lstw">16.1 This is sample text, another, and heading</h2>
This is my current code and it is not working sometimes. Please note KeyDown or set CSS through javascript is cannot use here.
public boolean userMoveHighlightText(String text){
String secName = "//h2[text()='"+text+"']";
getFrame(); // switch to iframe
By element = getLocator(secName, BY_TYPE.BY_XPATH);
Actions action = new Actions(getWebDriver());
WebElement content = $(element);
action.moveToElement(content, 0, 0).clickAndHold().moveToElement(content, content.getSize().getWidth() / 2, content.getSize().getHeight() / 2);
action.release().build().perform();
return true;
}

Answer 1

Replace the below code with the recommended:
action.moveToElement(content, 0, 0).clickAndHold().moveToElement(content, content.getSize().getWidth() / 2, content.getSize().getHeight() / 2);
Recommended:
action.moveToElement(content, 0, 0).build().perform()
//implicit wait
action.clickAndHold().moveToElement(content, content.getSize().getWidth() / 2, content.getSize().getHeight() / 2).release().build().perform();
