Start with the LogViewer implementation and reproduce the issue in the PatternFly demo at the linked complex-toolbar URL: scroll to a later line, then toggle Wrap Text. Trace the rerender and confirm that the fix preserves the same log location after wrapping changes, then verify the reproduction no longer returns to line 1.

Description

bug

Describe the problem
A clear and concise description of the problem. Which components are affected?

I'm using the log viewer component. When I scroll to a particular line, say line 100 > then toggle the value of wrap text > the component re-renders and I'm taken to line 1.

You can see this behavior in the demo here: https://www.patternfly.org/v4/extensions/log-viewer#with-complex-toolbar

How do you reproduce the problem?
Provide steps to reproduce. A codepen or codesandbox demonstrating the problem is appreciated.

  1. Go to this demo: https://www.patternfly.org/v4/extensions/log-viewer#with-complex-toolbar
  2. Scroll to a line, say line 100
  3. Toggle the value of the Wrap Text checkbox
  4. You are taken to line 1

Expected behavior
A clear and concise description of the expected behavior.

Even after toggling the value of wrap text, the scroll position should be the same.

This is important because if the user arrives at a log line much after line 1, say something like 1000, tries to read the log by wrapping the text, and is taken to the 1st line, it will be very cumbersome for the user to find / arrive to the same line again in case they don't remember the line number.

Is this issue blocking you?
List the workaround if there is one.

I couldn't find a workaround.
