Summary:
In the bedrock version, the light block is destroyed by the lava when the light block interferes with the flow of the lava. In the Java version, the light block just blocks lava. I believe that the bedrock version is more correct, since both the lava and the light block emit 15 levels of illumination, which means that the light block loses its purpose in the lava and only interferes with the flow of the lava by becoming noticeable.
Steps to reproduce:
Place a lava source.
Place a light block next to it.
Observed results:
Light block is not removed by lava.
Expected results:
The light block will be removed by the lava.

Is actually a duplicate MC-221590.
In fact, please reopen. In the bedrock version, it also stops the lava, but is almost immediately removed by the lava. The main problem is that the light block does not move away from the lava (not that it prevents the lava from spreading).
Watch the video:
However, this issue is closely related to MC-221590.
I think MC-221590 only considered the flow of fluids through the light blocks (this is how water and light blocks in the bedrock work in principle). However, my report is only about lava and the expected behavior is removal of light blocks with lava.
This also corroborates the comment from @unknown, which actually closed the report:
Intended / feature request. This is how waterlogging mechanics have always worked.
blocks cannot be waterlogged with lava neither in bedrock nor in java
Might relate to MC-234622.
