Chromium on Android acts weird with my HTML file. I repeatedly reload the tab, but:

• Some checkboxes are stuck with values that contradict the values that the HTML and JS code gives them initially. If I change their values through remote debugging DevTools and reload the tab, they go back to their weird values.
• All s, s etc. are greyed out and unresponsive in contradiction to the source code. They match :disabled seletors according to the "Styles" tab in remote debugging, but they don't have the disabled attribute/property according to the DOM and the Console in remote debugging.
• Despite reloading the tab, CSS classes of elements remain as they were assigned due to some user actions, not as they should be after a fresh pageload.
