Can TinyMCE remove caption="false" from images?

Question

JavaScript

When loading a picture, the TinyMCE editor adds a property: caption="false" - which, as it were, prohibits the display of a caption for the picture.

<img src="../source/statii/1557572548892.jpg" class="img-fluid" width="1012" height="505" caption="false" />

The manual says that you can disable: image_caption: true to false
But I tried nothing changes.
I would like to get rid of it altogether, which one I need in the tag.
Can someone tell me how to remove it from the entire site using JS when it is displayed?

Answer 1

You can remove an attribute.

allImages = document.querySelectorAll('img.img-fluid')
for(let i=0; i<allImages.length; i++)
  allImages[i].removeAttribute('caption')

But still this is not the best solution, but the answer to the question:
