When a casino slot game is loaded, text elements of the user interface are not visible.
Steps to Reproduce:
Navigate to an online bookmaker providing casino slot games. For this case I used https://www.quinnbet.com/ which is accessible from the UK. You will be able to load a game without having an account using free play.
Click on Quinncasino at the top of the page. In the search box on the right start typing the text white. In the resulting matches select the game White Rabbit.
The game will start to load and display the initial page.
The page loaded has the majority of text missing.
The page should display to include all text. The game loads correctly in the Chromium 70.0.3538.110 and Falkon 3.0.1-5 browsers.
Reproduces how often:

Reproducible on current live release (yes/no):
