    <p>It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy.

What it looks like initially when two divs are added

Answer 1

You can use grid-template-rows: auto 1fr; and it will fix your issue.

* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

h1,
h2,
h3,
h4,
h5,
h6 {
  margin: 0;
  padding: 0;
}

.grid-container {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-gap: 1px;
  background-color: #f7ca18;
  padding: 10px;
  color: #000;
  height: 300px;
}

.grid-container>div.item {
  display: grid;
  grid-template-columns: 1fr;
  grid-template-rows: auto 1fr;
  background-color: #f4d03f;
  text-align: center;
  font-size: 14px;
  overflow-y: auto;
  overflow-x: hidden;
}

.grid-container>div.item div.text {
  align-self: end;
  display: grid;
  grid-template-columns: 1fr max-content;
}

.grid-container>div.item div.text:nth-child(2) {
  position: -webkit-sticky;
  position: sticky;
  top: 0;
  background: red;
  align-self: start;
}
