Selenium - How to check if a "Load More" button is clickable/disabled?

Question

I gotta scroll down a list of articles from a Blog until I find a specific article. For that there is a "Load More" button which gives you more and more articles until there's no more articles to load, so the button disappears, it gets disabled (at least thats what I thought).

My idea was to have a "while" loop until the button gets disabled, meanwhile it would check if the requested article showed up:

public void scrollIntoArticle(String title){
        while(loadMoreBtn.isEnabled()){
            for(WebElement article : articlesList){
                if(article.getText().equals(title)){
                    scrollInto(article);
                    hoverAndClick(article);
                    break;
                } else{
                    scrollInto(lastArticle());
                    hoverAndClick(loadMoreBtn);
                }
            }
        }
    } 

However, it keeps getting an error: "waiting for visibility of element". Trying with "isDisplayed" I get the same issue.

So apparently the button never gets "disabled". The only thing that happens to the element is to get a new attribute on HTML: style="display: none;". For Selenium, "isEnabled" is always true, so the loop keeps going, "waiting for visibility of element".

I am stuck, cannot figure out what condition I can use to check if all the articles got loaded up without checking the "Load More" button. Any suggestions? Appreciate the help!
