Mask-image faded edges on all 4 sides with offset for scrollbars

trying to figure this out for a while.

I have a paragraph inside a scrollable (both axis) div with a mask that fades top and bottom edge. However, I need to fade out also left and right edge. There's a mask offset on the right for a scrollbar, same one should be at the bottom.

Here's the code:

.visible {
  height: 10rem;
  width: 20rem;
  overflow: auto;
  padding: 1.125rem;
}

.masked-overflow {
  --mask-image-content: linear-gradient(to bottom, transparent, black 20%, black 80%, transparent 100%);
  --mask-size-content: calc(100% - 1.0625rem) 100%;
  --mask-image-scrollbar: linear-gradient(black, black);
  --mask-size-scrollbar: 1.0625rem 100%;
  -webkit-mask-image: var(--mask-image-content), var(--mask-image-scrollbar);
  -webkit-mask-size: var(--mask-size-content), var(--mask-size-scrollbar);
  -webkit-mask-position: 0 0, 100% 0;
  -webkit-mask-repeat: no-repeat, no-repeat;
  mask-image: var(--mask-image-content), var(--mask-image-scrollbar);
  mask-size: var(--mask-size-content), var(--mask-size-scrollbar);
  mask-position: 0 0, 100% 0;
  mask-repeat: no-repeat, no-repeat;
}

p {
  width: 30rem;
  font-size: 1rem;
  margin-bottom: 1rem;
}

I tried to add second mask, but it takes only one of them. Also tried to ask AI, didn' help me with this one. This post is similar but has no offset for the scrollbars.

Solution

Using multiple masks will be tricky so here is an idea where I will add an extra wrapper to keep the mask easy

.visible {
  height: 10rem;
  width: 20rem;
}
.visible > div {
  height: 100%;
  width: 100%;
  padding: 1.125rem;
  box-sizing: border-box;
  overflow: auto;
}
.masked-overflow,
.masked-overflow > div{
  --s: 14px; /* scrollbar size */
  -webkit-mask: 
    conic-gradient(at bottom var(--s) right var(--s) ,#000 75%,#0000 0),
    linear-gradient(to var(--d,top) ,#0000 ,#000 20% 80%,#0000) no-repeat
     0 0/calc(100% - var(--s)) calc(100% - var(--s));
}
.masked-overflow > div {
  --d: right;
}
p {
  width: 30rem;
  font-size: 1rem;
  margin-bottom: 1rem;
}
