What leads the first element of a printed list to be enclosed with backticks in R v3.5.1?

Recently I updated R to 3.5.1 on may Windows 10 with RStudio v1.1.453. I am interested why the first element of a printed list is now always enclosed in backticks? Even if it is a standard name without illegal symbols, e.g., `a` as in this example:

# R 3.5.1

list(a = 1, b = 2, g = 9)

#> $`a`

#> [1] 1

#> 

#> $b

#> [1] 2

#> 

#> $g

#> [1] 9

In previous versions of R, the result looked like this:

# R 3.4.4

list(a = 1, b = 2, g = 9)

#> $a

#> [1] 1

#> 

#> $b

#> [1] 2

#> 

#> $g

#> [1] 9

Do these additional backticks have some meaning? Is it some kind of advancement? Or is it a side effect of some other R functionality? A drawback?

I tried on a R console and Rstudio (1.1453) on (R version 3.5.1 (2018-07-02) Platform: x86_64-apple-darwin15.6.0 (64-bit) )but couldn't reproduce the behavior, probably a windows issue dput(list(a = 1, b = 2, g = 9)) list(a = 1, b = 2, g = 9)

Seems like the same issue as stackoverflow.com/questions/50387825/unnecessary-backticks-in-r, although there's no real answer there

When is the fixed version of R going to be released? Will it be a patch v3.5.2 which will be released in a few months or is it going to be v3.6.0 and will be released the next year only?

Probably 3.5.2, I would guess.
